Okay... flashed Mystery's Sense 2.1 28014 and here are my thoughts.
Very fast and not buggy at all. I miss the Twitter tab, the way 2.5 formats favorite people, and the way 2.5 allows for ANYTHING to go into program favorites (the otherwise program tab). But, I think I prefer Sense 2.1's strengths over Sense 2.5's... but it wasn't an easy decision.
