Been there, done that, so it's time to move on. I've been swapping between 3 pulleys lately (61, 65, and 69) trying to decide what to run. The 69mm is the fastest for me out of the 3 when it comes to 0-60 times. The smaller pulleys just lead to more tire spin and slower times for my all-season tires. When I install summer tires this spring, I'll reevaluate.
