well i had it sanded to about 800 grit, man this thing is great now, it took about 1 1/2 games to break the track in, but after a bad 159, i went 235 and 237, this ball really opened up the area, especially on a synthetic shot, the entry angle is still awesome, thanks to the pro shop. I still have to keep speed on it, but it's not over/under like it used to be, I know what to expect.
