I played 716 AP2s setup to 1 degree flat for the last year. This week I did a fitting where we reviewed all club setups. My 5,6,7 irons showed that I was hitting them slightly in the heel of the club losing some performance. The 8-PW showed near center contact. The fitter recommended going to 2 degrees flat on the 5,6,7 irons and we saw an immediate 7-10 yards improvement due to center contact.
Has anyone else seen this type of improvement with mixed setups? Looking forward to a good start to the year when the weather breaks.
