Jake,
I have the Straight Flush, it's ok, you need to use it on totally burnt lanes, like in the summer.
I have the Big R Bang, this ball is great for dry lanes. Even by moving left, this ball has great length and tremendous backend. When it flips, the turn is great and the pins explode. I love this ball, when the lanes start to dry up.
Hope this helps!
