I've used the RCManiax one quite a bit and it works great. The biggest issue, using those bloody Corally blades. Despite the fact that they break pretty easily, they can also be a BIG pain to get back into the outdrives on the spool. Aside from that, even copping some pretty big hits, the outdrives are still in good condition. The only sign of wear is right on the ends of the outdrives as they curled up a bit, kind of locking the bearings on, but I curled them back with some pliers when I went back to the oneway. I don't want to keep a good set of ACER Ceramic Nitride bearings out of my car!
