I agree with all your recommendations, but I don't think it's worth it to retrofit my current mediocre regs to the dir spec hoses unless I can get them for a good price, how much would all those hoses cost? I can't imagine the 84" hose being cheap...
Nah, they're not bad. Check this out:
Regulator hoses | Extreme Exposure
Extreme Exposure in High Springs is not known for being cheap, either... $48 for a 7' hose is probably even high. But even at $48, it's a comparably inexpensive upgrade... And since regs don't typically come with 7' hoses (or any of the other lengths for that matter), you can get the hoses now and take them off your old ones and put them on your new ones if/when you upgrade regs.
That's the cool thing about modular gear... You can buy piece by piece.
Bottom line: Don't let it stop you.
I'm thinking of going this route for the price (currently diving a Zeagle Stilletto) to counter some of my leg heavy problem in the water. I'm still a new diver (~30 dives) and was wondering what you you do for ditchable weight with a BP/W? Weight belt? Add on pockets to the harness? FYI, I was using ~8.8lbs with a 3/2 mil on my last trip to Thailand, so assuming that I remove 6 lbs, I'd still need ~3-4 lbs to be neutrally buoyant.
It depends. Most people find themselves actually using less weight with a bp/wing - not just taking the 6 lbs off their belt - because the rig has less inherent buoyancy. There's also the argument that the wings dump more fully than a BC. Regardless of why, most people find it saves them a few extra pounds ASIDE from the 6 lb plate.
...So you might not need any weight at all.
Of course, this confuses the recently certified... "How do I dive with no ditchable weight?" My answer is simple: Don't dive with it in the first place.

It's ALREADY ditched.
If this concept really bothers you, then sure, dive with a weight belt... Or get ditchable pockets - there's several manufacturers who make weight pockets for backplates and wings. But the truth is, if you can swim up the rig with no air in the wing at all, then that's even better than ditchable weight in the first place.
I'd also like to dive Catalina or the Channel Islands at some point, since they are so close to AZ and I'd need a 7mil or drysuit there...again necessitating more weight.
Thanks! Sorry if this is a noob question...
Not at all!
Yes, the canned answer is, if you're diving with weight and you want to make it ditchable, then wear a weight belt or buy the ditchable weight pockets. The truth, however, is that if you can swim up with the rig, then you shouldn't need to ditch it.
My belief is that you should never ditch weight at depth anyway... In fact, shouldn't need to if you're correctly weighted, even in an emergency. You could simply swim up. Ditching weight at depth would result in an uncontrolled buoyant ascent.
There are people who will argue that uncontrolled buoyant ascents are just fine... Or a good last resort... Or that they can control an uncontrolled buoyant ascent. While I can, too, I still maintain that it's better not to ditch at depth in the first place.
