I've only bowled 6 games with mine and I love it. Drilled 4x3 with the pin under my ring finger, MB 2in right of my thumb. Drilled the same as my Reactive arsenal and Delta 1. 1/8oz side, 1/8 oz top and zero thumb.
For me, the Robo doesn't set up as quick as my Reactive Aresenal and is better on carrydown. When it turns its more of a continuous roll through the pocket that doesn't quit. Skid, rev and then Hook. Easy to line up with and still carried when playing in deep. This ball has a different roll to it, its hard to explain. A really strong midlane move but controllable, not flippy or snappy. Same great Track HIT.
