Thank you. That's quite helpful. From what I have read, it seems like the Pro Fli-Hi offers a lot of ball speed and good forgiveness for a driving iron. I'm looking to fill that elusive spot between my 3w and 4i. Accuracy off the tee would be where I would put the most importance.i have a 19* uw and a 21.5* fli hi. the uw has a ton more pop, whereas the fli hi is more about control. if i can get the fli hi in the air, anyone can, so i think that speaks volumes to where it fits in the driving iron segment. it isn't crazy low spin, it does elevate nicely, and it's decently forgiving. fwiw i've never tried any other driving irons, i just went with this one for some gapping. i've since acquired a jpx 923 fli hi hybrid at 20*, which is making a strong case to be the better club for my specific needs.
