If this is the case, the following discs really will do you no good:
Champ beast
2 Dx wriaths
Champ Monarch
They are too fast for the power level you are at right now. You would be better off setting these aside for now.
For drivers that leaves you with:
dx valkyrie
dx Leopard
Champ Leopard
Star Leopard
DX archangel
These are all understable drivers, so there is a lot of overlap with these discs. I'm not quite sure how I would decide what to throw with all these in the bag. I'd recommend keeping the Leopards as your control discs and choose either the Valk or the AA for your distance disc.
I'd also recommend a DX Banshee as an overstable driver. It is handy for forehand shots, thumbers, forehand rollers and other fun stuff. As you improve, you will be able to use it as a headwind driver. Sometimes you just need something overstable.
For midranges you have:
dx Shark
dx roc
These overlap A LOT. Pick one and shelve the other one.
For putts and approaches you have:
Dx avair
dx xd putter
Again, a lot of overlap between these two discs. Pick one.
I think that will allow you to simplify your game. You won't have to spend a lot of time trying to decide between which two or three basically similar discs you want to throw, and you can concentrate more on executing your shots.
Just my $.02.
Excellent advice ... three putt knows his stuff so listen to him
my only difference would be a Teebird rather than the banshee ... Ive tried both and I just like the Tee-bird in my hand better and I like the flight better
