After seeing numerous post here about the Mizuno MX20 being some of the easiest irons to hit, and having own a set on Comp EZ years ago, I found a very nice used set on fleabay at a really good price - dang these clubs go long and straight! Best irons I've ever owned.
Two weeks ago I was playing with my son-in-law who was using either Titleist or Pings and sliced his 5 iron into the wind on the last 175 yard par 3. I had already carved my 4 iron pin high. I handed him my 5 iron and he proceeded to knock it stiff and looked at the club in amazement! He said he'd like to have a set of these instead of doing the trade-in program with his current set.
I found him a set on fleabay last weekend, they came this past Monday and he played with them in his league Wednesday. He said he'd have to adjust his distances since they go a bit longer than normal but they went straight every time! So there's two of us that are happy golfers with these past model MX20 irons . . .
