The new hybrid Attention Star S2 from Roto Grip is going to be a huge hit. With eTrax Plus hybrid cover and coming out of the box at 2000 grit, this is the perfect complement to the Attention Star. I drilled mine 4 x 4.5 x 4 which has been my go to pin down asymmetrical layout and this ball really blends out the lane. Its a lot cleaner than the bigger asymmetrical solid balls but makes a similar controllable motion on the fresh. If you were in love with the Attention Star and just want something a little stronger, definitely purchase an S2.
