Want hook? This is the ball for you! Roto Grips latest addition to the HP-4 Line, NO RULES, features a brand new weight block. The Chaotic core has a 2.51 RG with .053 Diff and .018 INT Diff combined with the Micro DNA coverstock the ball motion this creates equals HOOK! At the 2000 abralon out of box finish, I found this ball to be the most hooking ball in my arsenal.
I drilled my No Rules with a 50° x 5" x 40° putting the pin above my ring finger. The ball motion that I get out of the No rules is that i can get the ball right and have no worries about it hooking back. The best part about this ball is that it never quits. Normally high end asymmetrical balls quit or roll out. This one seems to read the mid lane while still maintaining its energy and not quitting on the backend.
