I have had a Zuma for over a year and found it to be a basic wing which is all you need for warm water diving particularly bearing in ming weight restrictions on planes these days. I found only three problems with the Zuma - there are no quick release clips on the shoulder straps which i found a complete pain when i first used it - the pocket on the right hand side is not large enough for a reel and SMB and there are no D rings on the shoulder straps. I have cured the problem of the quick release clips by having two professionally fitted and am thinking of ways to have D rings fitted on the shoulder straps and i thinkl i will have to live with the small pocket. It has plenty of good points however - it is very lightweight compared to say the Balance - the weight pockets are a good size and clip in very securly and most inportant of all i feel confident using it even though it does look a bit flimzy. i will be using it next year on trips to the Red Sea and to PNG. hope this helps.
