I have yet to hit the MP-67 and was wanting as many reviews or help a possible. I have narrowed it down to these two and am not usre which I should go after. I am not able to sample both out on the range so any imput would be greatly appreciated. I have hit the MP-37 before and really liked them. What difference will I find between the two? Thanks for any help.

MP 67 is good club. You definitely won't find to swing with these. It's not hard like other blade, such as Titleist. The Mizuno engineer has made these club easy to swing with med-high traj.

The MP67 is a slightly larger-headed blade and, for me, gives a higher ballflight than the MP37. I found it played very similarly to the MP33. Relatively forgiving for a blade and quite user-friendly. Essentially it's an MP33 with the 'Cut Muscle' as a bit of a mid-life update.

The MP37 is a smaller headed iron, and is one of the more unforgiving modern irons that it's possible to find. I found it gave me quite a flat, piercing flight when I hit it - much lower than any other recent Mizuno offering - perhaps largely due to the strong lofts. The MP67's are a degree weaker in loft and gave a much higher flight for me.

Aesthetically, the 37 is a little less square-toed, and is fractionally shorter from heel to toe. Both irons have the traditional soft Mizuno feel and are obviously of excellent quality.

Of the two I prefer the MP37, simply because it offers the ballflight I'm looking for. The only caveat for me is that it suffers from a bit of 'Logo Overload' with a a surplus of Mizuno stampings on it. Silly perhaps, but plain is best for me and having two Mizuno logos on the back looks a bit daft IMO.

Then again, the MP67s have got the Runbird logo on the sole and I don't like that either...

Great information so far, any more personal experiences would be greatly appreciated. Thanks to you all.

I had a set of MP-37s and moved to the 67s when I got a new set. I felt like the 67s were a little easier to hit overall, and the ball flight for me was fairly similar, might have hit the 37s a bit higher but that was probably due to the shafts (tour concepts vs. project x). Also I had the lofts strengthened 1 degree on my 67s because I found I was hitting them a little bit shorter than the 37s because spin it seemed. Overall I prefer the 67s. They just feel a little more solid at impact and I feel like I have better accuracy with them. Both are great irons though, you can't go wrong either way I would say.

Hands down MP 67s in my opinion. In terms of looks, personally the 67s look more appealing to my eye. They might be slighly larger and I know they are more forgiving. I've hit both and like the 67s. I think for a good player they are the ultimate blade iron. I'm also not a big fan of the 37, overall. I think they are very demanding.

bump this for more views. any more experiences?

67's are more forgiving and have a mid trajectory
37's are less forgiving and go super low

Both feel like butter when you hit them well though

I'd choose the 67's myself

Seems as most of the love is going towards the 67's. I was able to demo one today and it felt just like every other Mizuno I have hit. First swing with it was one of the most beautiful shots I have hit in a long time. I had a hard time drawing the ball, seemed to want to fade. I am sure a lot had to do with my swing but still tought when I tried to draw it. Any similiar results from anyone?

neither .... mp-57's are the clubs
I couldnt get rid of my 67's fastest enough , not a good club

Tend to agree with those who have mentioned the lower ball flight of the 37's.
