Before someone more experienced than I chimes in, I would like to give this a go...

You appear to be just SLIGHTLY rev dominant, so I would put your sweet spot at about 110°. You have medium tilt and rotation, so ratios of 2:1 - 1.5:1 should work well for you, putting the layout at around 70° x 3 1/4" x 40°.

Ok, let the grilling begin ;)

Assuming you wanted a more aggressive drilling, to go with the aggressive ball and tighter shot, I was thinking 50x4x40, with a P2 or P3 weight hole depending on how it looks on the lane. Let's see what the Mo says.

I'm not too far from your recommendation. With the very slight rev dominance and the 15* of tilt, I like: 55 / 4 /40 with a P3 hole because the cover of the 920A is not that aggressive (medium at most).

I was so close! I opted for a little more length and a shorter pin :)
