I've used the magic rack at home now for a couple of years. I'm on the second one. Neither one gets all the balls touching. Usually turning the rack to a different corner helps but I don't think I'm getting much better racks than with a triangle.
I just watched Jason Shaw play Marvin Asis. A Phillipino i hadn't heard of. He had Jason down 8-4 but lost 9-8. Any way I looked him up on Fargo and it says no player found. How do you get to that skill level and not have a rating?
I think it would depend on the starter rating. Like Bob said they are usually set by the tournament director. If he set the two at 500 then they would be 550 and 450. Of course that wouldn't happen because being in a tournament they would naturally be playing other players.
I had the same issue with my Defy, I contacted customer service and shipped it to them. I paid one way shipping but they refinished the shaft and shipped it back no charge. I've had it back for at least a year and it's smooth as silk. I've only wiped it down a few times.
