haha i hated my pro model wheels, i completely destroyed them (wore them down to the core) in a matter of one month... i love metal cores, although sliders on them suck D*CK...thats why my next front wheel will be a 110 YAK...o and good bearings for under 20? bones reds, u can get them on amazon for about 12 bucks, and it comes in an 8 pack, so u have 2 sets of bearings =] i personally like them, and since im too lazy to clean my bearings, im gonna stick with cheap, fast ones like bones reds
