I'm only 13 years of age, and have just started to bowl with Track. I throw a 90 degrees angle, and about 10-12 revs, throwing about 14 mph.
I got this ball because I saw many people bowling well with it. I asked a guy about the ball, he said it was a versatile ball. When I got the ball, I noticed it worked well on Medium-Heavy lanes. If I have Dry lanes, I move to 35-40, get it down about 40 feet, and out to about the 5 board, and it MOVES! If the outside of the lanes went out, I played 20 to about 15, and the oil carried it down, and at the last second, breaks into the pocket. When this ball hits, much nothing stands up. Lately, I have been bowling at least a 210 average, when I am normally a 160-170 average bowler. After 5 days, I bowled a 279 with it, my highest game yet, with a 701 series. I HIGHLY recommend this ball for any lane conditions.
TRACK RULES!
