RE: which wheels
Good question!
I've become a bit disenchanted with foreign hardware over the past few years and have been using more of the standard brands like Goldberg and Dubro.
My favorite tire of late is the Dubro #250SL Super-Lite. I suppose I get 100-200 flights depending on the surfaces I'm flying off of. One thing I like about them is that they seem to wear off flat right down to the hubs without fuzzing.
I don't really run them down quite that far, but, let's just say I get my money's worth out of them.
