Though I wouldn't give 10 discs to a newbie in the first place...
I wouldn't put 10 discs in a beginner bag. I also wouldn't put anything fast in there, either.
Yeah, 10 can be too much if you're gonna be BH or FH dominate.
1) Putter - Any
2) Skeeter
3) Leopard (Advanced Beginner)
4) Viking
5) Valkyrie (Advanced Beginner)
6) Sidewinder (Advanced Beginner)
7-10)????
That's not bad but I'd swap the SW with the Viking. A Skeeter helped me tremendously when I was starting out. The Valk was the first driver that noticeably gave me nose up issues, so I usually reserve it and faster discs for discs to grow into.
3 Soft or Medium Wizards
2 DX Rocs
1 DX Shark (until one of the Rocs beats in)
3 Millennium (their base plastic) Polaris LS
1 Champ Banshee
Your putter and mid selection isn't too bad. I'd pick either the Focus or Challenger and the Roc for when you're on the course, but they'll all be good for field practice. Stop using the Roc for putting, too. It's for drives only.
The Pred is the only driver I'd keep if I were you. The rest of those discs are either too fast, too overstable or too squirrley to be any good for learning to drive.
Garublador always with sound advice.
My ideal bag for a beginner would be:
Putter:
Something that comes in a lot of plastic varieties, that excels at putting and driving, and something that if for some reason you don't like it you'll have no problem trading off. (
Wizard, Voodoo, Aviar, Challenger, Omega)
*caveat: The really DG illiterate would benefit from throwing a lid for awhile (Polecat, Gopher, Rattler, Birdie, etc.)
Mids:
Two schools of thought. You could get a couple from a stable mold and beat one to snot for an understable mid (i.e.
DX Rocs). OR you can get one mold that will be fairly overstable and mold that will be more of a finesse variety (KC Pro Roc & Comet; Z Buzzz & Fuse).
Drivers:
Speed 6 & 7 only. Ideally one stable driver (
Cheetah, Leopard, Gazelle, Cyclone, Polaris, Teebird, Eagle), one overstable driver that you can FH, OH, and throw into a headwind (
Banshee, some Eagle-X, EXP-1), and one understable driver that you can flip and turnover (
Leopard, Xpress, Polaris)
My biased picks (in technicolor):
Putter: (2)
S Voodoo,
Mids:
Z Buzzz,
ESP Buzzz,
Opto Fuse
Drivers:
Champ Banshee,
Glow Champ Gazelle,
DX Gazelle,
DX Leopard.
10th disc for schnitzengiggles:
ION (I told you it was biased).
