I know Efren was always noted a few years back as the best ball runner playing one pocket. I think there are a few now that run balls as well or better than Efren did. Shane, Scott and Alex for example. I know Billy I. and several others here could answer this better than I can? I know many young players like Justin B, Chip and a few others can run 12's very often, when giving up big weight. I watched a young player run 12 and out 4 times the other night. Opinions?
