My driver is my 173gr ESP Crush, Mid would have to be my 178 E Element, and my putter is an 173-174gr X Putt'r.
The number of discs I carry is dependent on either the course I play at or if it is a big tourney/new course.
I carry 12 discs in my Fade Crunch box, 5 drivers 5 mids and two putters (one of which is really used as a short forehand approach disc). In my Tourney bag I carry 21 discs. 3 really over stable drivers, 4 max distance drivers, 3 utility drivers and 1 under stable driver, 1 really over stable mid, 2 moderately overstable mids, 2 neutral mids, and 1 understable mid, 1 putter for 35' and closer, the same putter in a different plastic and slightly heavier for longer putts, 1 slightly overstable putter for dangerous holes and as bag filler (I don't like my discs leaning over in the bag), and 1 really over stable putter for short approaches and forehand touch shots/drives.
I carry mostly Innova but that's what I started with so it's most comfortable to me. I've collected some along the way and it's hard to get rid of some even though I don't use them as much as most others.
In my bag is:
Destroyers (long distance right to left)
Some Beat up Champion Beasts ( distance left to righty's )
ProLine DGA Rogue ( long,straight,fast & reliable disc )
Both DX and 12x KC Pro Rocs ( different states of wear )
Valkyrie ( another straight flier with great glide )
Champion Leopard ( currently working in but don't use it much )
3 same weight KC Pro Aviars ( for consistent putting practice )
Some lighter DX Aviars ( for further out long range putts )
..and a DX Hydra ( just can't get rid of her )
173 EcoStar Groove (favorite)
175 Star XCal (wind, hyzer forehand)
175 EchoStar Wraith
170 Star FL (easiest to control)
172 Star Sidewinder
175 CFR Whippet-X (does the same thing every time)
171 Star Spider (everything I need in a midrange)
Putt & Approach
167 Glow Aviar (go-to except into wind; also use as <200 approach)
175 Star Aviar (been switching between RW-Pro Aviar because the Star material is strangely too flippy-floppy for my preference)
favorite driver: 169g champion sidewinder/174g avengerss
favorite fairway driver: 172g beatup dx leapord (long approach shots)
favorite mid: 175g star coyote
favorite putter: 172g dx shark (for whatever reason it works great for me)

Orc star , destroyers pro ,11 kc pro eagle, 11x champ eagles, 11x kc firebird super flat , teebirds champ and star, kc pro whippet , star whippet , champion glow whippet, pro tl, leopard champ, star roc, kc pro roc, 12x kc pro avair, black 12x kcpro avair, 11x kcpro avair
I use the avenger on hole 12 at my course. I use it for a hard left shot even though its not meant for that. sometimes you have to manipulate a disc to work how you want it to. Bottom line is that the avenger is a understable disc that packs a punch if you us it the right way..enjoy!
