The targets to light the kickback come to mind. That entire right area is made to trap and deaden the ball, and usually ends in a right drain for me.

NF truly is the miss you're f'ed machine. Every time, if I miss, it drains. There are some days I hate Steve Ritchie.

I hated this at first, now on cannon shots, I nudge good (but not to the point of registering a warning) to the right when the ball hits the drops, this causes the ball the rebound to the right hard, and I have not had one left drain from this since. In fact, it works so well, that while playing "let there be rock", I can actually get a free hit on those targets to the right with the rebound most time.
