Anyone Have Experience With Mitsubishi MMT Iron Shafts

[3puttjay]

I'm getting some new irons and I always over analyze on my tools for any of my myriad hobbies. Golf is not different. I'm debating between steel and graphite for my shafts. I read up on shafts and struck by accurate the Mitsubishi shafts were in testing. Does anyone have them in play and what are their opinions on it. The stock graphite available with no major upcharge are KBS PGI and UST Recoil. Everything else has additional costs.

Shafts are such a personal thing. Is there a chance you could get a 7 iron made up with that shaft and see how it feels?

I can't get that particular shaft in the Ping i540 or the Titleist T250. The other graphite shafts that can be made with the 7 irons I'm looking at at are the UST Recoil and the KBS PGI. It seems I would have to purchase the Mitsubishi shaft and have it fitted with the Ping or Titleist adapter. I was looking for feedback on it before taking the plunge.
