Does anyone know a quick reference for how much weight to subtract when using a thinner wetsuit? I am planning to dive Bonne Terre Mine next weekend (April 1 & 2 anyone want to come?) and I normally dive an Aquaflite 7mm full suit with a 7mm shorty (they call it a jacket) over the top when diving the local quarries (45 deg temps). Bonne Terre is supposed to be around 58 deg and I don't think I will use my jacket, just a hood. If I remove the extra 7mm how much weight can I leave behind. It takes about 35lbs with both layers on. I weigh 270 and am 6' tall.
Thanks,
Bob J
