I’m currently playing Maltby KE4 Tour+ irons on KBS Tour 105 S shafts that are soft stepped by 1. Can I expect to get the same (or very similar) playing characteristics from Matlby TS3 irons on Nippon N.S. Pro Modus 3 Tour 105 shaft in Regular flex? Should I stay with Stiff shafts in the Nippon? FYI, driver swing speed is around 95-98 mph.
