Karl,

I am not quite sure yet as I haven't matched them up right next to each other.  I can say that by looking at the core characteristics and by watching other people throw the Deuce that the Rush definitely gets into a roll sooner and makes a stronger defined move.  The Deuce might out right hook more, but in a different part of the lane.  I do think you see more mid lane roll in the Rush.

Thanks,

I do recall when we were first designing this one that the EMB was the first ball that popped in my head.  But to be honest how many different core shapes are really possible with out getting somethign that might "look" similar?  It is bound to happen and has with many companies bowling balls.  The reaction of this ball though will not be anything like an EMB.  

Thanks,

My Rush definitely rolls heavier in the mid lane than my Top Fuel.  Due to the LOW RG of this core and our new coverstock this ball rolls sooner and handles some more head oil than the Top Fuel.  I still love my Top Fuel, but when you want flat out hook, roll and plenty of continuation with good hit on medium to heavier oil this Rush is it!  This is a must have in every bag as it reacts like nothing else.

Thanks,
