All my above likes are for purpose. So here I go. From a newbie stand point that wants to dip a toe in and try to race at the leagues. GO FOR IT. YOU WILL GET SPANKED ANYWAY. NOTHING TO LOOSE WITH TONS TO GAIN. If you want to run oil as a starting, to practice, to test, to try and beat your best graphite times.....go for it. I typically would not share my Knob Hill research. Rease is right. If you want to reprep graphite for oil follow his steps. DERBYBOYS is 100% right for Competition Speed they are trash. If you have some cuts that you spent good money on and will not be running graphite again and want to test the waters. Do it. Take notes. And once you have the cash or time or desire to pick up noticible speed recut some new Ws or purchase your best class wheels on from one of the fine vendors selling cuts these days.
