I was guilty of throwing a couple discs to be different.
1. Champion Monster - It seemed like everybody had a firebird and I could do everything with the monster that ppl did with Firebirds. now I need both.
2. DX Goblin - one of the first discs I bought. I could make it fly straight and didnt griplock it too often.
I scared the Goblin off but the Monster still lives under my bed
The one thing about my bag I've noticed is that I carry more molds than most.
Distance - Destroyer, Xcal, star Boss, Orc, Wraith, Starfire
Fairway - Teebird, Eagle, Banshee, Firebird, Monster, roadrunner, beast
mids - superRoc, dx roc, z-buzz, cryztal buzz, z-wasp, spider, gator, panther
there is only a couple that get used sparingly:
roadrunner - doesn't come out unless im in a tight spot, or get a crazy idea like a sky roller.

spider - windy putter and anny "s" putts
