I am renting all 3 mack daddy wedges, played back 9 kiawah with 3 other legends. The rentals performed just as expected (if dinged).
I can't say they are better than my clevelands, and doing close-in flops without a 64 wedge is a whole new experience!
Would I replace my currant wedges? For the price, no!
If I were allowed, I would replace my PW, buy the mack daddys, and still keep my 64 cleveland! Something to think about.
If they do have new clevelands in the product line to be announced it will be a difficult choice for anyone looking to get new wedges...my nickle.
