How it moves
Hockey-stick turn (asymmetric 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.
How much the ball wants to hook, 1 (straight, a spare ball) to 10 (the strongest oil-eaters). The maker publishes no number for this ball, so this is estimated from the coverstock, core, finish, and differential.

500, 1000, 2000 Siaair Micro Pad. 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.
