I've used a Retro Teal THS for a few league sets, as well as practice sessions, and the ball does exactly what it was designed to do, and what I hoped it would do! Drilled one with a 4 inch pin, 4.0 ounces of top weight, at 4 3/4" X 4 1/2" with pin high over ring, cg slightly shifted right of center in palm. Ball allows me to stay in an area without over / under so commonly seen by others. Smooth, predictable, and not overly aggressive. For me, my PAP is 5 1/4" over, 0 up or down, high track, and medium to high revs. Speed is 16 - 17 mph down the lane, and ball was polished lightly to make sure it cleared the heads for all 3 games. Not a hook monster, or sharp on the backend, but that is NOT what I was looking for or needed. Compared to a Supernova XP, OOB, with same drill pattern, mb just right of thumbhole, Teal is longer and a little sharper on the back.
