If you're looking for a speed machine, the buggy wheel on a revo won't help you anymore, because 1/8 buggy wheels have only 4.6" in diameter, so what you want is bigger wheel to reach higer speed.

BUT, the buggy wheel is lighter, and if you have enough place to gear it higher, this can be a good option.

If i was at your place, i would choose proline serie 40 wheel with 40 serie road rage tire
