This is not a “Krank review”, but it is a review of The Krank Driver-Formula X11. Who am I?.....a 70+ professional gentleman who has been playing golf since the age of 11. I’ve used persimmon, steel, aluminum insert MT Tourney’s, Bobby Jones, Titleist and Mizuno……..and as I aged my driving distances have tumbled from 240 -250 yds to just over 200. Over the past week I was lucky to return to the course I grew up on, Westmoreland C.C. in Export, Pa. I also played at the Jack Nicklaus Signature Course called Nevillewood. After using the Krank Formula X11, I can honestly say, ”hello to 20-25 extra yards” with the same effort. The feel as the driver head strikes the ball is secure, with positive feedback. So, what’s the bottom line?.......it’s worth a try for those looking for extra yardage without the extra effort! Plain and simple.
