I'm on dial-up here so can't risk cut'n'pasting from another site. Go to www.freegolfinfo.com and use their search facility.
Search for raw haze in the Equipment Forums (I think OEM Discussions) and you'll find a couple of posts related to this. I think the post you're looking for is "Mizuno Raw Haze sucks" - but it's only a grumble in relation to the finish. One of the responses to the post m does stress, mind you, that Mizuno expect the finish to wear.
I wasn't trying to put you off the club, but if you're taken by its looks, then sorry - but it won't look quite so pretty after a few rounds.
If that's not acceptable to you, it's best to change it now before you hit a few balls with it. Once it's used, the retailer may not consider "worn finish" an acceptable reason for exchange or refund.
