Any idea what is considered good, forgiving, etc. in MOI ratings in iron heads? Where does 2350 fall in? What is say the Epon AF-301?

It's hard to say what level MOI in an IRON is considered forging as for irons there are so many factors that affect forgiveness including sole, offset, materials... That said 2350 I'd say is average, the AF-301 is 2115. The AF-501 is 2437 and the AF-701 is 2399. As you can see the 501's actually have higher MOI than the 701's but the 701's are slightly larger and more forgiving overall.
