Just my $0.02, it sounds like you need to learn how to straighten out your shot and reduce hook. If you are using Avalanche balls and they are leaving flat tens or rolling too soon, a stronger ball like the C System will do the same but earlier and more. And a skid flip ball sounds like it would either hook too soon since it would be stronger than the Avalanches. My suggestion therefore is either to learn to straighten out your shot, or drill another avalanche line ball with a 6+" pin for more length. Again, just my thoughts...
