Doesn't look like it... I don't follow anyone, so I couldn't tell you.... I just happened upon the video on YouTube, was surprised to see Efren banging away so good, so I posted this on AZB
I think the BreakRak is the best thing for working on the break. In 10 minutes you can easily hit 50 - 60 breaks. It is so worth the investment in your game or at least my game.
I dont think I told you yet, but my son Jin won $100.00 at super billiard expo for the most consistent break in mph. Not exactly an Efren update haha....but thought Id tell you.
