I'm making my way through the DIR book, and find it to be the most useful book on diving I've ever read. It really seems like the smart way to go, and I plan to buy all DIR gear by Christmas for my Tech class. While reading the book and posts' on the forums, I've run into a buch of questions. For now, I'll only post three of them.
1. I need a little help on selecting a BP and Harness. I know that the Halcyon stuff is very nice but, is it really any different than say an OMS backplate and harness? I don't think OMS sells a DIR compatiable harness so, I'd have to make my own. Not a big deal but having everything ready to go would be nice. Is the Halycon BP and Harness really worth the extra $? I know that there are some people making BPs - FredT and Gary on Ebay. Are these BPs any better? I really want a nice BP and Harness as the core of my rig.
2. I understand how bungees on a wing could cause increased drag. However, wouldn't the bungees prevent the shifting of air in the cell, therefore preventing roll? I've never compared the two so, I don't really know.
3. I'm not quite sure how much lift I will require in a wing. What is a good lift capacity for tech diving using AL and Steel doubles? (AL when wet, Steel when dry.)
Thanks for taking the time to answer my questions.
