Well I can tell you this.  My Counter Strike on the Viper, if I played any sort of swing line out to 5 other than the line I was describing, it had no chance of making it back.  The line I was playing, the ball had a ton of energy going into the pocket and if I were to migrate in the ball would just want to hook early.  I shot 278 one game with 11 in a row playing that line.  On Scorpion, the ball hooks a little earlier for some reason, making the ball go through the nose.  Both my Rival and CS do this.  It's weird to say the least.  You would figure the way it's playing, I could move to about 18 throw to 7 breakpoint of about 5 and find something around there with either ball.  Problem is over/under, I'll get one board of play.  I'm feeling kinda adventurous, I might even try to say out around 15 with a breakpoint of 3 or so.  You know, they say a breakpoint more inside usually works on longer patterns.  This is showing to be true here, but I'm swinging from about 13 to 9 when I'd expect to play straight up 9-10 due to more volume and length.  When there's any sort of transition my CS is probably the worst ball in my hand since that ball straightens out at 20 feet when that happens, pretty strange.  I bet you I could take my Avalanche drilled 2 1/2" and throw it up 5-7.  I think I'm going to try it and if that overhooks, something is wrong.
