    I have purchased the Formula 11X driver and love it. My drives are 50%-75% more consistent. I went from hitting 4 fairways a round to hitting as many as 9 the last round I played. My drives have gone from 225 yards to hitting a 265 yarder this past round. And I’ve nick named my new Krank as “ The Kraken “. “Release The Kraken” can be heard from the other three(3) of my foursome on every driver tee block now.

    I am 60 years old and I just got the new F11PRO driver with the atmos shaft and I am averaging 30 more yards more than last year's extreme x. I absolutely love it and I'm hitting it straighter. I have owned several other drivers such as the epic and also taylor mades. This f11 with the atmos shaft is by far the best I have ever owned. I would definitely recommend this driver and after my friends see me hit it they just don't believe how far it goes. They say it can't meet the USGA standards but it does.

    My story to share for you… and its real. Listen, my friend George tells me that Krank sells a driver for slower speed older fellow like myself at 71 years of age – was hitting 200 some of the times, until I got the Krank driver. Well, call me, email me, visit me, I’ll show you that I now hit 250 often of the times, otherwise 220 guaranteed… and that is after a few driving range practices and a half dozen games – I’m actually improving yard by yard.

    I recently purchased the Formula 11 Pro Krank Driver and it is absolutely amazing. It has a great feel and a perfect weight making it easy to control. I have never been more confident out of the tee box. Lastly the sound of the driver is amazing. I love the look that I get from friends and strangers when they hear the awesome sound that comes from the driver when the ball explodes off the face! I'm a Happy Customer.

    Just an update on this F11X driver. WOW, I'm sending you a pic. This is a 327 yard drive with the new driver after dialing it in. I over shot the green and you can see im on the back fringe. I went from 260 yards on Ping G30 to 285 plus with Krank. Dialed it in worked on my form and have hit several shots over 300 yards. I cant thank you enough. You need proof im it. This thang is awesome when you figure out your mechanics.
