On this game you should be able to hit the left ramp cleanly with some momentum and have it consistently go up. Not a ton of momentum, mind you, but a slow moving inlane roll. You probably won't be hitting it from a dead stop. That wouldn't be any fun anyway as it would make that shot a ramp rape.

The center ramp is a tough shot and should be. That's the jackpot shot. High risk high reward. Not only do you have to hit it clean, you have to hit it with momentum, and if you fail you're probably losing the ball.
