I played the front 9 of St georges with the full set of rocketballz and they are a lot of fun playing the links style of golf (ie running it in from the front) i don't think they'd be suited to a course like bethpage though because you just can't stop the ball quick enough.
They'd be good for players who struggle with a fast meter but not legends as the long irons just don't compare to the R11's or Burner 2's. The more lofted irons stop ok though so from the master tee's they can be very accurate as it's very easy to ding it.
