Deciding what angle of the flippers work best on RFM or any later machines.
1) Flipper resting on toothpick (without rubber)
2) Flipper resting on toothpick (with rubber)
3)Lining up straight angle with inlane guide
Any opinions ?

I generally set up Williams games with the rubber on, and the toothpick between the rubber and the flipper body (which also assists in keeping it aligned while tightening).

Not sure if this was the intended way to set up (although I was told by a long time pinhead that it was) and it seems to work well.

Specifically done this way on my RFM and I like it that way on that game anyway.
