hi all. if you have dry suit that is a bit to big, does this affect weighting, i have a tri laminate, i think its to big, and the boots as well. i seem to have too much air in it. the si tech auto dump valve i dont trust, had it not work a few times. i am on 12kg lead, and sink ok, but end of dive when i hit the 10 mtr mark, i really struggle to stay down, and not do a rapid assent , getting a bit pissed off with dry suit diving. in a wet suit im like a seaoned pro.
