As per the specs on XR irons, the stock shaft lengths are:
6i = 37.875"
PW = 35.75"
AW = 35.50"
SW = 35.25"
So, your 6I + 1" now is 38.875" long.
If you have already extended these two wedges 1" also, then you would extend their shaft length by 2".
If you have not already extended your wedges, you would be increasing the shaft length by 3".
A couple of things to consider:
Shaft length + loft helps determine how far a given golf club will launch the ball. If you make the wedge shafts 2 to 3 inches longer, you likely will get yardage compression. You might get a PW that flies longer than your 9i.
Safety factors: The clubsmiths at GolfWorks do not recommend extending non-putter shafts beyond 1". You run the risk of creating shear points, with club possibly coming apart.
If you like longer shafts in the short clubs, try the single-length irons.
I will be posting some next week sometime. I have been in the Fitness business for 20 years. These will include 3 levels for beginners, intermediate and Advanced so you can work your way up. I will also include some easy warm up drills. watch for my posts "Ten minutes to better golf " check out my ten minutes to pain free golf in the meantime
I as blown away this morning when I saw the new Cleveland woods and irons in Golf Digest.
At the 2015 St. Louis Golf Expo, the regional Cleveland/Srixon rep had told me that Cleveland was going to focus on wedges and recreational clubs, while Srixon would focus on clubs for competition golfers. I noted, however, that the past 18 months the Cleveland site only talked about wedges and putters.
So, it was good to see the GD ad on the new Cleveland Launcher woods and irons.
Circa 2009, the Cleveland CG16 irons lost out to the Callaway X20 irons when I was redoing my bag. And, I played a mix of CG14 wedges until last summer.
Good to see Cleveland rebounding beyond wedges and putters.
Several golf club manufacturers have used variations on CB in the designations of their cavity-back iron models. I doubt such a suit would go anywhere; it would be like trying to copyright the terms grooves and dimples.
