Kevin - Go with the TakeOffs man! Especially if you are running the Novak USTC race in Jan. You can't beat the price on the tires. $32 (?) for a set of four! The sorex Rubber ONLY costs over $30 including tax. Then you have to include the $10 for inserts, and the $8 for the wheels themselves. It's just not worth it when the Take Offs run just as well.
With the TakeOffs, make sure you get a good scuff run on them before you accually use them in a heat. I know when I first ran them, I was sliding all over the place the first practice. After about 5 laps, I came in, re-saused them, and finished off the battery. After that, the tires worked well, although they are shot now!
You don't need a lathe. If you see me cutting my motor, just bring your armature over, and I'll cut it for you.
Edit - I just estimated the cost of a full set of Sorex. about $49. Take Off, With Racer Discount @ Trackside ends up being like $32, preglued..
