Well what you wanna know? I already shot a 772 and an 813 with it. I LOVE this replacement for the Storm Spectra! It's a ball 1st out of the bag to start off with almost every league I've bowled. I can't express how well this ball rolls, and yes, it gives you some area to work with. I left the surface right out of the box, never changed anything. I had it drilled almost exactly the way my Spectra was drilled. My 813 I stood 27 with my left foot, rolled over 16-18 at the arrows and out to 8-10ish at the break point. (it was on wooden lanes, but my 772 was on synthetic lanes) With the factory Reacta Finish and the R3S Pearl Reactive coverstock, This ball rolls amazing. Specially with that Vector Core and I will continue to roll this ball! For me, its a medium oil ball, and has great back end, not a snappy reaction, nice - smooth - and very controllable!
