Save yourself a pile of money and get one of these drivers. And I didn't pay an arm and a leg either, like you might buying one of those other top name drivers,580's,983's,427's,redline. It is by far the longest hitting driver that I've ver hit. I even out drive him from time to time with my new Hi-Cor driver. He was out driving by 40 to 50 yards.It was starting to get to me that he would fly right by me when before we were about even, then I decided to get a 400cc driver myself.I purchased a golfsmith Hi-Cor 11.5 degree driver and now we hit our drives about even. My best friend bought a $300.00 Golf gear Tsumani 400cc driver and was killing it off of the tee.
