I don't have quite as many dives on mine as TS&M (40 maybe) but so far no zipper zipper issues. I do wonder how people with poor shoulder mobility get on with it though, I can just get mine done up before I can no longer rotate my arm, on a stiff day I have to use my left hand to push the zipper closed the last cm.
I got the fusion with the tech skin and so far love the mobility it offers and how easy it is to control the bubble inside the suit. Not that I found it difficult before getting a fusion, but the stretchy skin makes a pretty big difference.
I have only one complaint about the suit. The pockets. They're crap. My grievances against them are:
1) They are tiny, if you want to carry wetnotes, a spare mask and a dsmb/spool its a tight squeeze
2) They're made of the same material as the suit. This helps in fitting everything I want to take with me in them because they stretch but it makes getting anything back into a pocket (unless its my wetnotes which get their own pocket) quite difficult. It makes getting things out a little trickier than it should be. It sticks to my mask skirt. It makes the pockets really flimsy and almost impossible to get things back into.
3) No sewn in bungee, just grommets. At least there is a place for a bungee, which is an improvement over previous whites pockets, the the bungee knots are annoying, I'd rather just have a nice loop or two of bungee sewn in, or at least have the grommets at the bottom so I could have an upward facing loop.
Aside from the pockets I think its a great suit.
