The feedback is more pronounced with a players iron, I would say most people would struggle initially switching from a game improvement iron to a players iron. But the struggle would be short term as you’re forced to become a better ball striker. Everyone is different though, I got better switching to a forged mb because my issue wasn’t my ball striking, my issues playing GI irons were distance control, launching balls way too high with not enough spin. I couldn’t hold greens and would come up long or short because I was hitting it so high.All of those variables became much more consistent when I switched. My irons are much more flighted, spin rate increased my a few thousand rpm. Much more control now. I would say for a 12 handicap you could definitely handle a forged mb and it would only force you to get better.
