well. all i can say is that this ball is just as consistant as my nighthawk.  only difference is that it has a more agressive coverstock.  the performance is just as good.  mine is 15 lb with a 3 in pin.  my drilling pattern is ur basic 4x2.  the pin is set right of my ring finger, CG kicked out, with a balance hole on my PAP.  i dulled this ball down with white scotch brite, and finished with clean and dull.  i did this so i can use it where i bowl.  they dress the lanes 34' i believe, but they don't strip the back ends, so there's usually a lot of carry down.  my storm eraser and black thunder (both polished & both with strong drilling patterns)couldn't do anything on this pattern, got lots of inconsistent reads which made it hard to make adjustments.  though im finding that the 2 houses i bowl at don't use a lot of oil during the day (lots of senior bowlers (leagues) in the am), the shot is usually 32-38ft, with or without carrydown.  on this day, i was able to play down 10 and the ball rolled true and hit the pins solidly.  it doesn't leave too many 10 pins, and you can make quick adjustments without having to wonder what the ball will do.  the coverstock is very tweakable.  polished or dull, you can use it on a variety of lane conditions.  the power ring core is a great match with the coverstock, which is a particle.  you can use it as a bench mark ball, and it compliments the other nighthawk balls great.  If you can find one, get it.  oh.  im new to this posting stuff, so if you find my review vague or you just can't simply understand it, let me know, and i'll work on it.  thanks..
