I am thinking of buying a 2nd hand set of Ping Red Dot ladies golf clubs. Would anyone be able to tell me if Ping red dot would suit a senior lady (early 70s). I play 18 holes once a week and 9 holes twice a week, on foot. I'm a bit confused about the blade type and don't know if they are suited to low handicappers or mid to high handicappers. Your opinions would be appreciated.
