-hh once bubbled...
The bend radius of a strap going through a QD is roughly 3x greater than going through a BP.
Let's take a specific example...
Check out the actual measurement of a Scubapro Classic or Knighthawk and a Scott Koplin "standard" backplate. I see virtually no difference in bend radius.
Any item is going to have what is its "weakest link". On metal BP's, this bit of replacing the webbing every ~2 years is it.
Well...
If that's the bp's weakest link... And admittedly, it doesn't seem to me to be a serious issue when it can be solved every two years for $12,
strictly for cosmetic reasons... then I'll select a bp over a "regular" BC every time. It sure beats the alternative... Including issues with trim and buoyancy, fading, wearing out, replacement every few years for comparable cosmetic reasons, stability issues, "riding up" issues, and of course, broken plastic connectors.
You consider this maintenance to be an acceptable cost for all of the other benefits you believe the system has. For diving doubles, you're right.
Why would singles be any different? Furthermore, why force yourself to purchase two different rigs for two different dive situations? Wouldn't it be a benefit to have one rig that can handle all of your diving? Wouldn't it be a benefit to become accustomed to one rig, where all of the D-rings and connectors and straps are in the same place? That can do wonders for "muscle memory"... The ability to judge where things are without having to look. Furthermore, why would you want the added stability (over a "regular" BC) in a doubles rig, but forgo it in your singles rig? Would you not want the benefit for all of your diving?
Insofar as the beratement of conventional BC's, including all your criticisms, you're guilty of making an overly-broad generalization in order to try to make your case.
My generalization comes from diving around 30 different BC's over a period of about 150 dives. You're correct to say that it's a huge generalization. If you'd prefer to take this debate down to specifics, I'd be happy to. Feel free to name brand names and model numbers, and I'll be thrilled to give you my opinion of them. I can't promise that I've dived every BC that you could name, but I've dived a number of the most popular models.
Dive gear these days is really pretty darn good, even the cheap stuff. And the typical recreational diver today don't need the "Cadillac" BC or regulator, even though it will offer them some improvement. Unfortunately, the message today is "buy the best you can afford", and we have forgotten that Better is the enemy of Good Enough.
Agreed.
If the diver feels that it's "Good Enough" to select the BC that isn't as durable... Doesn't help with trim and buoyancy... Isn't as stable... Isn't as simple... Isn't as easily repaired... Well, then... Perhaps they don't need the "Cadillac" of BC's.
If you want "Better" gear, that's fine...just make sure that it is really so. And don't berate me when I point out that "Good Enough" also gets the job done. This is merely recreational diving, not the first ever moon landing.
-hh
Well...
Firstly, I'm not going to "berate" you. If you feel that I have done so, then my apologies. It's not my intent to attack you personally. In fact, it's not my intent to "attack" at all.
Secondly, your comment brings up a really good point, which is more the intent of DIR than the issue of gear selection. You say, "This is merely recreational diving, not the first ever moon landing."
Agreed... We aren't looking to land on the moon here... This is diving. However, you've nailed the very crux of the difference between DIR and "everyone else." While your claim that this is "merely recreational diving" is true, the entire mindset of DIR is one that takes the entire diving experience much more seriously. To the followers of the DIR dive style, the "group" isn't referred to as "the buddy system," but as "the team." Divers are encouraged to live a "diver lifestyle" that includes regular exercise, the "cleaning up" of bad habits like smoking and alcoholic consumption, and eating a more balanced diet. Divers are encouraged to learn decompression, the dive tables, and a deep understanding of the physiology of diving. They are encouraged to select "buddies" with great care and dive similar rigs such that problems are equally understood by all parties who are affected by an issue... Not to mention that possible "fixes" in gear are readily available, since everyone's diving the same stuff. DIR encourages divers to learn, understand, live the lifestyle, and be "into" diving much moreso than any other training program I've been exposed to. GUE calls this a "holistic" approach to diving... That is, "all encompassing" (not "holy" as in "sacred.")
It's simply a different approach... And may not be for everyone. While the major agencies that I'm aware of preach understanding, education, and a healthy lifestyle, it's simply been my experience that DIR/GUE takes the approach a little more seriously. That may be for some, but I understand if others don't want to "be a diver" but simply want to "dive occassionally." It's a choice that depends completely on your mindset and what you deem to be "right" for you.
...Which is why it's so entertaining to those of us who dive the DIR style when someone says, "I'm 90% DIR." The very point of DIR is the holistic approach, and acceptance of anything less than 100% means that the holistic approach has not been adopted... Meaning that the person is simply not DIR.
...Which is okay for those divers who choose not to be DIR. But they're fooling themselves to claim that they're a "percentage" DIR.
The bottom line here, -hh, is that you've focused this debate on gear... The "tools"... Of diving. My mindset - or at the very least, the one that I consider ideal - has little to do with the gear, or the "tools," and instead has to do with a "mastery of the basics" of diving. To me, the very best that can be said about a tool is that it helps you to get the job done, and does not interfere with the task at hand in the meantime... In the case of diving, that "task at hand" is the enjoyment of the dive. To me, gear failure is nothing more than a tool that detracts from the enjoyment of the dive. To me, diving isn't about the gear... It's about the fun of diving... And so I get super-annoyed when my tools prevent me from having a good time.
As such, what is important to me is gear that is either bulletproof or easily fixed on-the-spot. In some cases, this includes underwater fixes, such as the ability to repair my second stages underwater during a dive.
...Which is why I've selected gear that I've come to find fits that bill as closely as possible. No gear is infallable, but it's my humble opinion that the gear I've selected, in this case specifically a bp/wing, suits that style of diving best. I've simply found that I'd rather place my life in the hands of a metal backplate, the absence of breakable components, and replacable, one-piece harnesses than the options you describe.
The only safer option I know of is to not dive at all... And that's simply not an option.
