I don't like the "motion hole" layout for lower track players. In my opinion you'd be better served with a pin down layout and the "double thumb" positioning of the x-hole.
My PAP is 4 1/2 over, and I tried the motion hole layout and that particular ball quickly became a paperweight compared to other layouts that work better for me.
The Gold Rhino is a very good ball when it finds friction. My advice is don't go crazy with layouts, and match up your surface and you'll be fine.
