I would be interested to know how much weight is normally needed for dynamics. Everyone else seems to use very little or none at all, but I use 4kg with a 3mm suit. I tried to do some dynamics with my 5mm smoothskin and 4kg of weight, but it was impossible to do more than a few metres with or without fins, as I was using a huge amount of effort to stay under. I splashed along the surface, kicked one fin off and made everyone laugh!
I read in another thread that Tom Sietas used 10kg of weight for his dynamic record, so it couldn't be a bad idea.
I like to be slightly negative at 3m and slightly positive at the surface, both with full lungs, when doing dynamics. This has never caused any problems - sometimes people ask if I am ok with all that weight, but there has never been any problem with getting to the surface, even when I am very tired.
The only disadvantage of needing so much weight is carrying it to the pool. I learnt an important lesson - it's hard to do statics after carrying a heavy bag around for a long time! :duh
