The only problem that I had was this. I think that my neck seal got flipped out at the back of my neck upon one of my ascents. Is this just from not venting fast enough?
14lb seems like a lot of extra weight to add for a drysuit. Is this normal? I was using a 3mm wetsuit and my drysuit is a DiveRite 905.
Can you give more details of your suit? ie is it membrane or neoprene, is the neck seal latex or neoprene? A neoprene neck seal should be turned "inside out" against your neck, a latex seal shouldn't. If you have the seal too high up your neck it can give problems as you move around. If a latex seal is loose and you don't vent enough you can burp air from it sometimes. I recently changed from a latex seal on a membrane suit to a neoprene one, and am much happier with the neoprene.
14lb doesn't seem an excessive weight addition over a 3mm wetsuit (6.4Kg), could well need more, depending on undersuit etc. If you think of the volume of air trapped in your undersuit (especially with a membrane suit and a thick undersuit) then think that you will need over 1Kg of lead for each litre of gas.
