I use white randos on my cutter. As stated above, they're not the most durable tire made, but they give really consistent skids as well as a solid feel.

For my commuter, I use the cheapest tires I can find. Right now I think I have "detonators", which is a terrible name for a tire, but they were like $5 apeice. I used to have gatorskins and they felt like poo, so I didn't see much point in paying a premium for them when I can get cheap tires that also feel like poo.
