Well, since this new section's here, I'll call a spade a spade and admit that this is relatively still where I am (being relatively new to DH diving at least).
Was in the pool the other day in my full wetsuit because I was fooling around with my twin tanks (after sitting for a year forlornly in the corner...), and I decided to bring PRAM #1 and a LP72 to test out some other modifications I did to my single-wing (as opposed to the micro wing from before). I think I've managed to integrate the DH nicely with the other components in my kit - and they actually play nicely together
(if you look carefully in the video, you'll see my twinset and al40 now sitting forlornly on the ledge above - at least now they're wet!)

...admittedly though, my pool session with the double-tanks and single-hose was just FUBAR. Plus all those bubbles around my face! Yep, going back to the DH was like coming home. Quieter. Smoother. And breathed a lot better too! Definitely all my single tank diving will be done this way. And why can't there just be more LP72s in the world?! Those tanks are the best!
