Solid Rock Golf, thanks for your response.
I am not sure I understand what BBGM is, can you explain for me?
Here is what Carlton said in an earlier post about Riffle shaft installation and a 5.0 flex Rifle, do you agree?
"A Rifle flex rating will only be accomplished if the club was built to Rifle standards, i.e. a Rifle flex of 5.0, is only a 5.0 when your 2 iron specs are D3 at 39" length, has a 2.5" hosel with 1.25" tip insertion. There are math and science involved when it comes to installing Rifle shafts."
Thanks,
Gary
