Brett (or any others), I’m in serious need of advice! I’ve played Maltby for decades and have built a great many Maltby clubs for others. I’m now in the 80s (age, not score!) and the distance has diminished drastically. My current irons are STi with MPF Pro Series in A flex. Unfortunately, I lost a lot of distance when I went to this combination and I suspect the shaft is a poor fit for me at this age. I’m tempted to give the new KE4 Max a try (the pics look great!). I’m at a loss as to what shaft to try. MPF890? Any advice would be truly appreciated. (Also, can the KE4Max be bent 2 degrees upright?) And thanks for making this forum available.
