I do. However, I'm slightly overweighted with just two lp108's and no lead. Also, they're extremely difficult to manage (especially full) compared to al80's. I will never be able to dismount one of the 108's and hold it out in front of me like you see these instructors do in videos. Maybe I'm weak, maybe the tanks are just too heavy for that, maybe both. I like pumping them up to around 145cuft and getting 96cuft as my third, though.@bluemed
Just curious, why aren't you guys using steel tanks with the drysuits?
If I ever dove water cold enough that my lavacore was insufficient undergarments then it might be a different story. Thus far the lavacore is good to about 65f for lengthy dry dives.
I know, people say "if cost is a factor you shouldn't be doing any technical diving." I do okay, but I'm not Bill Gates. It's a factor for me.
I always tell people I started sidemounting because I needed doubles and it is a few hundred bucks cheaper to do than backmount doubles. Either way you need 2 regs, a bcd, two tanks. Backmount also requires a manifold and bands. Also, when you double up tanks with a manifold, it's such a pita to install/remove the manifold that you're pretty much dedicating the tanks to doubles. If I want to use one of my tanks for a single tank backmount (or sidemount) dive on a boat.. no problem.
I guess if you're already in BP/W and you only needed a bigger wing, it erodes some of that cost difference vs buying a sidemount bcd. It doesn't completely eliminate the cost factor, though.
