Shift kits must be a preference thing. I like my Stage-2 kit in the C6 in my '53. I've also got extra cluthes and a manual/automatic valve body in it. I really like the firm, positive shifts. The harder you get on the gas the more snappier they are. If you are light on the throttle, it's actually fairly smooth. Also, with my transmission, since it has been rebuilt with new parts, I have the ability to run different fluids. Right now I am running Dexron III. The rebuilder told me if I switched to Type-F, the shifts would be a bit firmer yet. Given the Dexron III and my shift kit, I think it is a good balance right now. Also, my truck was built for cruising, not racing or a daily driver, my neck ain't sore either
