I got my first set of clubs aged 10, Wilson, red and white bag signed by Bernhard Langer(a memorable xmas as I immediately smashed a glass lampshade swinging the driver), switched to ping at aged 14, and there I stayed swapping ping models for 10 years, while on holiday in florida I went to a pro shop in Orlando planning to pick up a full set cheap for a few rounds while my girlfriend hit the Disney parks, after 5 hours testing irons I discovered the MP30s(so it wasn't the cheap set I planned), I'd never felt anything like it, they were like an extension of my arms, the iron glided through the ball and hitting that sweet spot felt so soft and perfect, I've used them since, along with Taylormade woods. A couple of weeks back I went with an open mind to look for a new set, I took 4 iron sets up to the test lab, the Nike pros, callaway, ping and the mizuno Mp4s, I asked to leave the mizuno until last, after hitting each club in each set I got an mp4 in my hands, everything just clicked into place, it felt like shaking hands with an old friend, the weight was perfect, the shots were true and that feeling of a hot knife through butter when striking the ball was back. The tech said straight away that I looked so comfortable with them and all my stats on the laptop looked great with them. Went through to same process with woods, wedges etc, all now mizuno apart from my 15 year old trusty putter! Not only do the mp4s feel incredible, they are also the most beautiful irons I've ever seen. Now have to wait for them to be put together, should get them in 3 weeks, other than the pitching wedge, the components arnt available until mid August.
