Pros: These irons are beaultiful, great feel, lofts are perfect, and workability is superb.
Cons: The soles are not cambered, hand made so not cheap.
My MP-29's were not run of the mill. I have played some mini-tour golf, but more importantly I have a friend, from Sweden, who has played with the big boys. Because of him I was able to get a totally "Tour Custom," as they call it, set of 29's 1-PW for next to nothing ($200). They were swing-weighted, shafted, grip sized, and most especially factory ground (before chroming) to my specs (with a cambered sole). Which Mizuno will only do for their tour players. I had them for almost 4yrs before I totally wore the faces out, at which time a Mizuno rep got me a set of MP-14's, but that is another story.
I have been playing blades, of one sort or another, since I started playing golf. Not because I was good, but because old blades are all a kid from my background could afford. The 29 is one of the finest irons ever made (they are hand made). The workability is just phenominal, and can really only be appreciated by "Plus" handicappers, which I am when my game is on. But to watch a tour player use them is just fascinating. As good as I am my friend usually gives me 3 a side and still beats me by one or two, 2 out of 10 times I may beat him. In short, 99.5% of the people who use these irons, me included, will never use them to their potential.
That said, you can always aspire to reach their potential and your games potential, and that is what they are all about. If you have the money and more importantly, the time, you will fall deeply in lust with these irons. I say lust because it is less analytical than love, and when, or if, you actually stop to think about buying and playing them you will say,"What the hell was I thinking?" That is, until you see or pick them up again. Good luck.
