Not hitting shorter irons long enough

[Sirduffsalot]

Hello, 

 

For some reason my 9, PW, W are going short. I expect 10-15 yard increments. What I getting is a much shorter distance. The gap is 20-30 yards. Checked the loft on all the clubs and they are right on the correct loft. I am playing Titleist AP 1. I changed the shaft to the Fiber/Steel shafts. Recently, after considering the weight difference between Kuro Kage shafts and the Fiber/Steel shafts. So I increased the head weight two swing weights on the 9, pw, and w. The yardage increased. Still not up to my Pings.

 

Any suggestions or tip. I am ready to hear them. If all else fails, I bought a new bag to make the irons easier to sell.

When I was having a similar issue a few years ago it was because I was flipping my hands at impact, causing me to lose speed and add loft

Especially with 9 on down... Put the ball in the middle of your stance and try to hit it low. Easy way to remove a hand flip or scoop at impact and keeps your hands ahead of the ball better. Ball will come out lower but with more spin.

Thank you for sharing;

 

I am currently working on my body rotation and swing around my spine. My back is acting up right now so I am flipping my hands.
