Can someone recommend a ball that has a cover/core combo that is more "rolly" than sideways off the spot?  I prefer a hard arc reaction down lane as opposed to the hockey stick.  Thanks for your help! 

Anyone who has never tried a Venom Shock has truly missed a "special" opportunity.  This ball is so versatile on so many different oil patterns (medium, medium-light, light, and yes even medium-hvy).
Simply put, if I could only have one ball to bowl on a THS anywhere is the U.S.A. (and I have bowled on a THS all over this country), it would be the Shock.  I say this having owned a IQ Tour solid which would be number 2 for me.
