My Tron has 1200+ plays on it since I got it less than 2 months ago. I wipe the disc with a dry rag on occasion, and black grit comes off it. My disc will throw that ball out of there like its stung out on crack at times, and other times it's pretty tame when it comes out of there. I think a lot has to do with when and where the ball is gripping the disc before it gets ejected.

Mine will have so much spin on it at times, that it will shoot straight down the middle of the PF, with so much back, and side spin on it, it actually reverses, and travels up and thru GEM. Freebeeeee!!!

Other times it comes out of the disc with so much overspin it actually accelerates when it hits the PF.

Just my 2 cents....
