I agree that a well-geared 6-speed should be more flexible than a 5-speed.
Bill, I might be wrong but I believe the '93 964C2 should be a /03. I don't how much that will matter. I don't have any track experience with either my old 993 or my current 964, so my subjective opinion is one based on the driving I do (large city, suburbia, and rural twisties). I never warmed up to the gearing of the 993. I'm more comfortable with the 964's 5-speed. YMMV.
