I voted lid. If I had a second vote I would have gone for putter.
TurnBurn suggested this in the original thread and the idea is my #2 choice for this disc:
I really got into the Innova Stud because it was advertised as a shorter, slower Roc. This sounds fabulous on paper. In practice it doesn't quite hold up. There is not enough HSS for the Stud to carry the Roc comparison. The Stud is *okay* but I still want to find a shorter, slower, small diameter Roc-putter for cycling.
If we get a second vote then this is what I vote: keep everything about the Stud... low profile and all... but make it more HSS.
