I use a Teebird as a fairway and Wraith with for driver so a Thunderbird would seem to be nice. Nope, hated it. Try and try but it gives me nothing good. Into the bin it goes.
What? Did you try it in Star? The Star Thunderbird is an overstable piece of crap. The Champion Thunderbird is my go to controlled hyzer shot disc, I love that thing.
Mine are:
DD Convict: the thing is overstable until a butterfly flaps it's wings within 50 yards. Then it turns into a flippy unpredictable mess.
R-Pro Pig: R Pro is crap, and this disc wasn't even really OS. The grip sucks too.
Sidewinder: Most inconsistent mold I've seen. Flies like the convict but worse.
