[Hack84]

ok so my set is all stiff but im looking to get a 3,4 irons but i dont know if i should get them stiff aswell of get them reg.
i have 2 hybrids and i cant hit them (i know thats weird) but when i hit my buddies 3,4 iron i smash them so i dont know if i should get a reg or a stiff what would i gain or lose from getting one or the other



Thanks Hack 84
