I play a lot (upwards of 5 times a week sometimes) b/c I live 2 minutes from a really nice course.
I use Innova discs: a 175 Cobra driver, 175 Aviar putter, and a 150 Leopard.
I agree Wes, I've yet to see a point for "mid-range" discs. I can drive most medium holes, and the long holes are either so crazy long that I have to drive twice or I set up just perfect to "drive" a putter for my second shot.
I'm mainly a two-disc guy, the Cobra flies ridiculously straight or will perform soft, long hyzer/anhyzers on command. My putter is both my approach disc and my putter, I usually throw a big, high hyzer on anything around 100 feet, and a dart from anything closer.
I only use my Leopard for super long rollers (thrown huge anhyzer to get it to land vertical -- sometimes these go 250 feet

), or insanely high tomahawks from 150-200 if monster trees are protecting the pin.
When I play a lot, I usually score 55-57 on a pro-par 54, and when I don't play a lot I'm usually around 63 (my drives get horribly inaccurate and I can't seem to hit a putt outside of 20 feet).
