I always dive dry as well, but in Sidemount or CCR the lighter trim better than the heavy. In BM, yeah would prefer heavier (unless travelling with the fins)It's a risky gamble for that price! I'n guessing shipping will be around $40 AUD. I currently use either XX-L jets or I think XL F1s (I'd have to check that though, could just be L).
Probably would want to wait for the heavier version as well as I'll always dive dry.
