I'm considering getting a bp/wings setup, and need some help with the right size of wing.
I intend to dive singule tank, mostly al80 or lightwhight steel. water here tend to be rather worm, so I dive 1mm in summer and up to 5-6 mm one-piece in winter (size L). With the al80 I need about 4# weight total durring summer and about 14# in winter.
I'm abvioslay thinking about getting a light BP, probably aluminum. I may also need a STA.
What I don't know is what size wing I need, and I would like to get one that is as small as posible. My calculations say that 20 should be OK (not that you can get such wings), and that 25 and above is a safe bet. does this sound reasonable, or did I get it all wrong?
And if I ever move to doubles, what would work right there? would I need more then about 5# extra (to compansate for more air used), or would I need to add extra for safty or other factors?
