How it moves

Foul lineArrows · 15 ft40 ft · board 6.54.5° entry
Arcing turn (symmetric core). Dotted is skid, then the turn, then the roll into the pocket. Estimated from the coverstock, finish, core, and differential for a right-handed bowler with medium revs on a house shot. Lane conditions, speed, and layout move all of this.

1500 Sanded. Sanded then smoothed (1500 to 3000 grit): enough tooth for oil, enough gloss to get down the lane. Most box finishes. Surface changes over games, and a pro shop can take any ball either way with a pad.
