i used mine for the first time on monday night.
drilled it 70* x 4 1/2 x 25*, w/pin under. left it oob.
typical house pattern on guardian. i was able to play the track area, as well as go in and swing the lane. the ball would come back from anywhere. the only problem i had was my carry wasn't the greatest. operator error i am sure. lol!!
will try it on synthetics this weekend and see how it rolls, before i make any surface adjustments on it.
the ball clears the heads well and makes a nice solid motion off the spot. not really flippy, but strong. i think a lot of different types of players would like this ball. i have seen guys who twist it more than i do (which is not hard), and those who are a little less than me, and they love their reaction as well. overall, another solid ball from Hammer!!
