My irons from last year were made 2 deg upright. Since then, I have altered my swing based on a recent fitting I find I need to add a deg upright for a total of 3 deg upright. I added the additional deg to one club (7i) to try it out and I like it. So, my question is: what effect will adding a deg upright have if I do this to all my clubs? Does it affect loft for example? What should I be careful of? Can I do this all clubs, 5i-GW? Thanks.
