Hi Sir Bowl,
Your span is almost the same as mine. I'm 6'-2" and 215lbs. I roll at about 15-16 mph. My PAP is similar to yours also. 5-1/4" over 1/4" up. I have two of these. One drilled 4 x 4 and one drilled 5.5" x 4". Obviously the stacked ball is much stronger. But I love the one drilled for earlier roll. It allows me to add or subtract hand as needed to get the corners out. Translation= carry. It usually sends pins flying all over the place, depending on the amount of side roll, or hit I apply at the release point. Of course it's your choice. But this is just a tidbit to get you thinking on what drilling you might actually like. The stronger piece is good also, but as lanes transition, I find I actually have to move with the transition in order to carry effectively. Hope this helps.

JJ
