My pro has done some video reviews of the new toys Mizuno have been putting out the last few weeks. They are all good and I would take a look if I were you, he is a top Mizuno fitter and great and enthusiastic coach/pro.
A really random one caught my interest yesterday.... The New JPX Fli Hi... I did own one of these (now sat in the shed looking brand new). The old one was UGLY!! This however looks very very interesting.
It just looks so hit-able. I would have totally overlooked this, I use long irons but could easily see myself taking these for 5 and 4 iron. I wont cos my irons are new but in hindsight I would love to build a set of clubs with these in.
Check out Andrews other videos, hes a good guy and knows his stuff.
