Hello everybody,
I've been puzzled for some time picking the right wing and made this small excel spreadsheet to assist me. It helps choosing the right lift for your wing/BC, picking enough _and_not_more_ lead and shows your buoyancy at the various stages of dive.
Start with section 1 and see how the table changes and the required lift/amount of weight are displayed in section 2.
Post your feedback/suggestions here or pm/email me.
Enjoy!

It has to be in excel or similar spreadsheet - there are dynamic calculation.
You can download openoffice (openoffice.org), I believe they have mac version as well.

When you are on the surface a part of your body - usually head - sticks out. This way you can breath not compressed air and talk to your buddies )
When the head is above the surface it contributes to negative buoyancy. Since average head weighs ~10# that's how much compensation we need to keep it above surface.

BTW, I just uploaded an updated version, which can calculate lift for both weight integrated (lead on rig) and non-integrated (weight belt) BC. There are some substancial differences between the two.
Also, any suggestions for calculating exposure suit lift at depth? I had no idea what to put in this cell for my 7 mm wetsuit and 6/4 mm hooded vest. Thanks!
