I have both balls, and as described by others, The BITE has more of a "Skid Flip" reaction, while the ANGER is more of an arcing ball. Much as I've tried to label one or the other as my favorite, they have become my "co-favorites", as they are both great balls.... just in different situations.
I've had more consistent outings and higher overall scores with the ANGER (averaging 220-235), as the early rolling shape of it's trajectory is more predictable. But with the BITE, I can get the ball deeper and I have had higher highs (289, 280) and therefore feel I have the potential for a much better (higher) game.
In short... The BITE is a little harder for me to line up with my target, but once I do, the sky is the limit. With the ANGER, I'm more likely to consistently line up with my target, but it's rare that I bowl anything over 230 or so with it.
