Grabbed an orange star TL3 in max weight off Innova factory store a couple months ago just to try it out. The one I got is extremely flat-topped. I've found it to have just about the perfect amount of stability. Dead straight with a little finish at 75% power and finishes slightly to the right on max power throws. For me, it has replaced both the Leopard, which I've used for a long time (better hand-feel I think and less touchy), and the FDs which I've been messing around with, which I want to like, but never quite fly the same for me from shot to shot. This has been a great, controllable disc for woods tunnels and panning anhyzers. Only problem is I ordered a backup from Innova recently just to have in the trunk, but the new one is much more domey. Haven't thrown it yet, but classic Innova mold inconsistency.
Anyway, the one I've been using is a great disc and one I throw multiple times a round now. Will be in the bag for the tournaments I'm planning this spring.
