I am going to do the Flywheel weight thing within the next two weekends. I spoke with the folks at Aloop.com on Friday. They told me the biggest weight they installed was an 8oz because of the clearance problem. Who else does the flywheel weight inatall with the 10oz weight. If I send it out to someone I don't want to wait for two weeks to get it back....Tha's the only advantage with Aloop as they will get it back in two days ready to be reinstalled for the weekend.
