Hey bud! First of all when I got the mp53 I was playing off 14 but my iron play has always been the best part Of my game! Comparing to the x20s is tuff as they were in standard specs. Shafts and lie angle! If I'm honest fitting for the correct shaft has made the most difference j believe! I'm 1 club longer than I was with the callys! The feel with the mizzys are so good but there is still enough forgiveness if you catch 1 thin! No where near as forgiving as the callys but there is still some there! My golf has improved aprox 3 maybe 4 strokes since switching to the mizzys! Like iv said I honk that is due to the fitment! I also hit the 800pros it was very close between the 2 but I needed less offsett so went with the mps hop this has helped
