arent the full carbons suceptible to cracking when hitting pot holes and such ?? I know they are lighter , but I dont have the money to be replacing these often, I'll buy one set every 200 years if i' m lucky.. LOL..

Full carbon Zipps are prone to cracking. I weigh 190 and I built myself a nice set of Edge 68 clinchers. I have destroyed many wheels... Rolf Vigors, multiple Mavic Ksyriums, and Cosmic Carbones. The 68s are the stiffest and strongest wheels that I have ever owned. I have yet to put a wrench to the since the build. That is pretty impressive considering that I can trash just about anything. I have a couple of buddies in town that are starting to make carbon saddles and rims... Guess who they put on them for strength testing.
Edge rims light years ahead of Zipps in terms of technology being employed.
Their rims are rated to higher tensions than Zipps. They build laterally stiffer because of it.
They cast their spoke holes in order to keep the flow of carbon continuous.
They use internal instead of external nips in order to reduce the size of spoke holes that hurt a rim's integrity.
They autoclave their carbon which uses less glue and more carbon. In order to stay competitive Zipp sands their rims down so much that they tend to crack.
Alloy clinchers being stronger than carbon ones is a myth made up by companies that do not want to spend the money developing a very advanced technology.
