Yesterday I was sucked farther towards The Dark Side on three dives in the beautiful San Juans. Bowing to unrelenting pressure from The Evil Queen (aka TSandM) I opted to put my tanks into/onto a BP/W (Halcyon Wing!) and then attach same to my body and then jump into the dark green Puget Sound. Not just once did I do such a thing, but Thrice (and I lived to write about it).

So, what was my experience with a BP/W instead of my beloved back-inflate Balance?

#1 -- Note to self -- when doing major equipment changes (and I believe changing BC's to be a major eqipment change) make sure that you don't skip "kitting up" steps AND that, regardless of peer pressure, DO A FULL HEAD-TO-TOE equipment check. I didn't do that and very shortly after getting my head underwater I realized that I had forgotten to plug my dry suit hose into the inflator -- and then later remembered that I really didn't have a tail now but instead I had a crotch strap! Fortunately it was a pretty trivial thing to hook up my dry suit hose and the trailing crotch strap didn't catch on anything.

#2 -- A back inflate BC is a back inflate BC. The BP/W I used actually felt almost identical to my Balance. After three dives I really couldn't tell any difference in how this felt as compared to my BC. In both cases I was stable, I seemed to trim just about the same (I couldn't tell a difference at all), the tank felt the same, etc.

#3 -- The only noticeable difference I could tell was that the BP/W was a bit more sloppy than my Balance! Now this was totally unexpected BUT I think I know why. I dive a full neoprene dry suit which means that it compresses with depth (unlike the crushed neoprene or trilam suits) and I'm quite used to cinching up my Balance as my suit compresses -- something I can't do with the Hog rig BP/W. So while it was fitted properly in the kitchen, once I got down below 40' it got a little loose and I couldn't do anything to fix it.

#4 -- I remembered from diving years ago why I hate weight belts and why I LOVE my integrated weights. I don't have hips -- my ribs come all the way down to my hip bones. Having to use a weight belt again was as painful and discomforting as I had remembered -- and again, as soon as I got any compression in my suit, the weight belt became loose! (Of course there are solutions to that should/when I ever do the BP/W route.)

The upshot of my brush with Death, Darth and the Dark Side? I SURVIVED!!! Nope, I shall continue to resist and wage war against the Evil Queen with my Cobra, Back Inflate BC, Split Fins and Air Source.

However, I must give a public Thank You to GratefulDiver for letting my approach the Dark Side -- knowing that I have survived.

Thank you Bob. (Oh, and want to borrow a camera? That is, if you'll be back before WE leave!)
 
Perhaps you had it a bit too loose fitting the harness in the kitchen?
 
That crotch strap that was trailing behind you will make a world of difference as far as stability. I know with mine, if I leave it off the rig does not like to stay where it is supposed to.
 
Well, no convert there . . . but I got a friend to try my Jets in the pool yesterday, and she surfaced with a grin a mile wide and said, "I can FROG KICK with those!" So a little progress made in my campaign of assimilation, just none at home :)
 
Well, good to see you have resisted the demon and stepped back from the abyss Peter...:D

Seriously, good for you, trying it out to see what it was like. I too will be stepping into the dusk, if only for a moment next month. I firmly believe that although DIR or semi-DIR may not be for me, I am going to take some tech courses so I can have the experience as well. There are many good procedures and skills to be learned and I think the same way you do. Take the best pieces from ALL sources to improve my diving.
 
TSandM:
Well, no convert there . . .

It may be my fault Lynne, I dropped the kool-aid into the harbor when getting on the boat. If we had slipped some of that into his stew after the first dive, I think he would have come over.

Bwaaaa haaaaa haaaaaaa . . .

Hey Peter-let's dive again soon, I promise I won't bring the kool-aid, really, I won't.
 
Well, good on ya Peter for giving it a try ... like all gear, it's just a tool. Some folks prefer Craftsman, others prefer Snap On ...

And some buy the really cheap tools that are on sale at Home Depot at Christmastime . . . :)
 
Interesting. Re the fit. Always had to reseat and adjust a jacket BC once I got in the water. Easy thing to do and an easy habit to get into. However once I got the first dive done and everything adjusted the way I want in the BP/W I only readjust when I change from dry to wet/cold to warm. No need for that first two minute adjustment I needed in the jacket on every dive.

I dive a trilam though so perhaps that is the difference, and also hated the wrap around of the jacket style from the first time I tried one so was an easy convert. Just a thought. Suspect the initial adjustment in the kitchen was incorrect. Had to do mine in the water and fine tune it at the end of the dive. Now it wont work any other way as the straps have a permenant groove in them.
