Also like my SR300, but need length, too. GB10.7 is very aggressive - when I play the track area or the heads fall apart, the ball loses energy quickly, despite the higher RG core.
Searching length, I sanded mine witha grey pad, then with 2.000 grit Abralon and hit it with Brunswick High Gloss Polish. From the looks, there is little difference to the OOB finish. But the surface feels definitively less tacky, the ball should move even better through the oil than before.
Haven't used it yet, hopefully tomorrow in training on a short pattern, just to see if it goes better down the lane. I'll post results if I get any.
Since the ball surface calls for 70% of overall ball reaction/performance, it is wise to start here if things are not going your way. Plugging etc. should only be final measures.
BTW: ball polish is NOT car polish. Car polish will seal the ball's surface, clogging the pores which create traction. You will more or less kill a reactive or particle ball with it, on a polyester ball it is fine. I'd always use ball polish or compounds, and a soinner to apply it.
