The OP did not specify that he didn't want a steel plate. I wouldn't buy any MARES BC. Too many reports of issues with them and their integrated weights. I just looked and the thing also has 40lbs of lift. For single tanks that's nuts and unnecessary. The d-ring placement is a joke, the inflator is a Mares design instead of a basic standard inflator and size large weighs nearly 9 lbs. My al plate and 23 lb wing is less than 7. I also would not buy a BC that wasn't completely modular. Especially for traveling. The ability to replace only parts of the system would be my primary concern. I have traveled with a SS Plate a number of places. Never needed to take my al plate.
I have a Mares Pure SLS - bought it from Leisurepro. (Hint: I bought it by buying the Hybrid Pure which is still listed for sale, and they got back to me saying it was discontinued and I could get a Pure SLS for the same price. Paid $230 for a $400 BCD)
Its a really nice BCD. Lightweight, the integrated weights are nice, has trim weight pockets as well. I was able to put this BCD, reg, wetsuit, and all the accessories into my carry-on to Cozumel and it weighed around 30lbs. It has D rings in all the right places and even a roll up pocket under the right weight pouch.
The trim pockets are placed slightly higher than the belt (vertically), for what I can tell, they are fine (but it depends of where you place your tank). Curiously I'm having a better attitude with the Mares than with the XDeep (where i placed the trim pockets higher than that, at the middle of the tank).
My wife has the pure and loves it.
