Sways I tried anything from the 1.6 up front to none and 1.4 in the rear to none at all. Settled on 1.4 front and 1.0 rear gave me the best feel all around. I do want to note that I am not a spool fan. I showed up to the race with a diff front and rear. I never could stand the feel spools give coming off of the straights felt a bit too bound up and would scrub too much speed. I HIGHLY recommend getting the new red ano cups for your spool. Something about the anodizing and the blades got rid of all that and helps carry the speed very well. After I put mine in the spool stayed in the entire week. Definitely changed my mind on spools!
