Drysuit/BC for bouyancy compensation

[flyboy65]

It didn't dawn on me until last summer that using the drysuit for bouyancy control uses the same amount of air as my BCD would.  In my little world it always seemed like I'd have to use tons more air if I used my drysuit. 

I always use my drysuit.  It's nice to get rid of the squeeze.  If I wanted to use both...it'd be pretty tricky finding the right amount of air for either device.
