The Pyga I'm riding now came with a set of Crests on Hope. I bought it off a mate of mine who first had the wheels on his Rocky Mountain then on the Pyga so they're probably 2+ years old....he is well over 90kg's and rides through and over rather than around things and barring one ding on the back they are 100% and have seen PLENTY mileage...several stage races etc. I'm over 90 as well and have had no hassles and I certainly don't baby my bike or my wheels...mostly singletrack, G-spot etc...very little dirt roady-ing. Depends largely on your riding style as well....whilst swapping them out is probably the right thing to do I certainly would not lie awake at night concerned that they are going to collapse the first time you throw your leg over the saddle. (That said I have a set of Arch's hanging in the garage waiting to be built onto the Hopes when I DO finally trash them Crests....) Oh ya and a well built wheel using a Crest is going to be a lot less prone to picking up a buckle or a wobble than a poorly tensioned Arch EX for that matter.
