I have a really clean GnR with Rev2 ramps. It had a 23-800 coil in the launch when I got it which was clearly causing problems. I replaced with the recommended 22-600 and there would still be stuck balls. I've tried to dial everything in and it's still unreliable, which is a bummer because I'd like to put the game out for people to enjoy but I can only keep it in our private club because every night, by the end of the night, I look over and there's 6 balls in the shooter lane

Someone looked at my launch kicker and it was concave instead of convex and suggested that might be a problem. I can see how that might impart a little more potential force to a ball, but I can't imagine that would make that much difference. I was debating pulling some windings off the 22-600 but I looked and there is a 20-400 DE coil available - not sure what it was originally for. It's got a resistance of 1 ohm. I'd love to have something that could theoretically push 2-3 balls out of the lane if it needed. Anybody tried that?

That's what I thought. I figured the difference in velocity is marginal. Do most people have the concave ball shooter?

I'd really like that, but not sure for $500. If you're negotiable, let me know. I was thinking about trying to create my own wireframe as well.
