So i ponied up the $9 and thought I'd give it a whirl since it most likely supports MSG in some way. I had a custom fitting last week so i took the numbers plugged them in and got my results.
My fitter suggested and Epic Flash for me and so did True Golf Fit so thats pretty good. The issue I have with the tool is the fact that it does not provide driver loft and really only suggested stock shafts. I think the shaft addition is just them adding the stock to the tool and adding $2.
It's not a bad tool but for $9 and a one time try, its not worth it IMO. It's just OK and a bit of fun and i used it more for validation but by not adding loft to the suggestion is a huge miss.
It's a cool concept but I won't be a repeat customer.
