Changing Lofts on Ping G15 irons

I have stiff G15 irons that I hit plenty high. I am not compressing the ball. I was told I'm hitting the ball on the upswing. However, I play once or twice a week and I am hitting the balI where I want it to go, so I am probably not going to mess around with my swing. I hit my 7 iron about 145, my 8 about 135, my 9 about 125 and my PW about 110-115. I only hit my UW about 85, my SW 65 and my LW 45. My shots are sky-high with these three clubs. I am thinking about decreasing the lofts of 4 clubs. PW from 45 to 44, UW from 50 to 48, SW from 54 to 52, and LW from 58 to 56. Ping charges $5 per club to do this. This will reduce the bounce of these clubs, but the PW and UW will still have 9 degrees and the SW and LW will still have 10 degrees. In addition, the courses I play usually have packed sand and tight lies so I think I will be fine with less bounce. My question: Will I get any appreciable difference in length with these clubs by doing this, or would it be a waste of money?

Those are the exact distances I currently hit my short irons and broke 80 the past two weekends for the first time. Improving your swing mechanics will do more for your distances than force lofting your clubs.

Popping up the wedges is a swing issue so fiddling with the lofts will only slightly alter your yardages. You are likely scooping at the ball a bit.

Get a lesson to get better contact with the ball. This is an elemental swing change.

Also, increasing the lofts on the shorter clubs could mess up the gapping of our entire iron set.
