it doesn't matter at this point but the best rim IMO hands down was the Orion rim which is no longer made and we have all been using RP handouts for so long that we got away from mounting our own tire's. I too am curious to know what rims are durable and don't warp so easy. So far I know that xenon rim don't warp but they do crack fairly easy. Next up on my list to try might be the Yokomo rims or the speedmind rims.
