Comment on Trampoline

Does anyone see any real difference between Bullseye and Trampoline? I notice that it's now UB, as already mentioned, and that it looks a little sleeker than Bullseye did, and now additional "discs" can be opened to represent folder contents, but... I dunno, it seems like not a lot to justify doubling the price. Maybe it's just me, but there are so many launchers out there. I use Trampoline because of the free upgrade from Bullseye, which I registered before I knew that the free Quicksilver can do radial menus; had I known that, I probably wouldn't have been able to justify Trampoline's cost.
