They put this pattern down for some of the locals to try one night, newer wood lanes, good condition.
The only guy who really had any area was using a big blue pearl, sanded to 1500, pin over the bridge, mb swung out in the track. He is a normal 3/4 tweener, 16-17 mph, and was playing a slight swing from 10 out to 5 or 6. Strange drill (at least i've never seen it), but he was bowling significantly better than everyone else, and he is not that much better than everyone else.
Hope this helps...
