I have a G* FB, Orc, EX, and TB(factory 2nd) bagged atm. The Orc has seen a ton of action, including hitting some rocks, a couple roads(hard), and of course trees. There is barely a mark on it. The FB is starting to get a couple marks on the rim from hitting trees and spike hyzers, but still flies like new. The EX and TB have only seen a little bit of action so far, but they fly exactly like the numbers would suggest.
I think people have gotten so used to what the discs fly like recently(super OS molds sold as normal, i.e. FBs, TBs, Destroyers, Eagles) that they no longer come close to the numbers. G* seems to be the most true to the numbers I've ever seen from Innova in a premium plastic(meaning not DX or pro). In that frame of mind I think G* is a resounding success. If you're looking for the most OS meat-hookiest firebird or most OS version of anything, G* is not what you're looking for.
Innova has nearly every possible flight covered, now they're giving us more options. You can cover the same shot with a more OS disc in G* or a less OS in Champ and still get the same flight. Just depends on your preference. Think of it like an engine, you could have a V8 that puts out 400hp or a turbo v6 that puts out the same 400hp. Two routes to the same goal.
That's my take on it(as retarded as it might read).
