Before all the smartasses  chime in I'll go ahead and admit I am on the fat ass side of the scale.  Know that I got that out of the way, here's the problem.  I paddle a Jefe and use a Astral rescue pfd.  I find it difficult to bend forward when setting up to roll.  Are there any other rescue vests on the market that have the floatation distributed more evenly and no so much around the gut.  Also can anyone give me input on putting foam in the seat to lift me higher in the cockpit of the boat. 

Thanks
Trevor
