I tried my friend's out today on the range (5,6,7,9,PW), Stiff shaft. They have a small footprint and a thin topline. However, when you hit it square, it has awesome feel/feedback.
It has a similar size to the Mizuno MP-67s but it is more forgiving (given that is more of a cavity back rather than 'cut muscle'.
I don't practice enough to justify playing the 'player's clubs'. I just enjoy the forgiveness of 'off centered hits'.
After hitting those, I felt like I was swinging a Hummer H2 with my own clubs (MX-900).
