I'm new. I'm 40 years old. Been playing about 6 months. I'm about a 30 handicap and happy with my progress. I should have already, but I'm going to start lessons next week. I'm playing right now with hand-me-down Powerbilt game improvement irons, which feel like rocks. I'm going to get fitted for new clubs.
Preface: I can work my sand wedge -- with face open or not, half swing, full swing, etc. -- and hit straight and consistently drop balls at 20 yards, 40, 60, or 90. Consistently.
Question: I know general wisdom says that I should be playing "game improvement" or "max game improvement" irons, but am I crazy to think that players clubs in the lower irons, maybe PW, 9, 8, would be a bad move? If not outright blades, would game improvement clubs like Mizuno MP53's (which are supposedly for scratch to 14 handicappers) in those lower irons. If I can work a bladed sand wedge well from the fairway, rough, bunkers, etc., I don't see why blades in the lower irons would be such a stretch. I was wondering if someone with more experience could educate me as to if/why I'm wrong.
