I would ask what type of riding you think you will be doing and how much do you weigh?
If your riding is harder trail riding and you are over 80kg, I would go with the wider, heavier wheels.
If your riding is more XC without many drops, roots, and rocks AND you weigh less than 80kg, go for the lighter, more narrow wheelset.
I learned my lesson with my DT Swiss XR1450 wheels. My weight is ~90kg and I ride some fairly rough trails with lots of rocks and tree roots. I loved the light weight DT Swiss wheels but after only a few months of riding, I bent a rear wheel enough that it could not be brought back to true. I purchased a new XR1450 rim and replaced the one that was bent, however I'm sure I will bend the rear wheel again in the future. When I do, I will rebuild the wheel with a carbon hoop from Iplay.
My other bike has Iplay 30mm carbon rims and Bitex hubs. I've ridden these wheels pretty hard and they are just as true as when they were new. They seem to be much stronger than the DT Swiss wheels but they are 1560g. For me and my riding, I need the extra weight and strength of my Iplay wheelset.
