I like Joe Talavera's take on such things. There are issues that impact the function of the team, like having equipment in the same places, learning the same procedures, using the same gas. And then there are things that only impact the individual diver, like what material your dry suit is made out of. As long as the suit fits correctly, permits adequate range of motion for reaching valves, etc., and has appropriate storage, I don't see how it impacts the team whether it's trilam or crushed neoprene.
I'm buying a compressed neoprene suit for the insulation properties. I'm willing to deal with the weight and the drying issues.
DIR is about being a THINKING diver, not a lemming.
