Well I used the same weight as I normally do and I was having a floaty feet issue. A quick purchase of spring straps and that was sorted.
Second dive I ditched a couple of KG

and I'm sure once I'm more used to this drysuit malarky I could drop another KG or two, not quite the 6-8KG that Endo had me hoping I could drop, but still, it's good news.
So a full 7mm wetsuit and overjacket is more bouyant than a membrane drysuit and arctics.
