Mizuno's are softer - I have no doubt. Played the 33's for 2 years and played the 690mb's for several months now. HOWEVER, the U grooves on the mizuno's create too much spin. Also, the sole grind of the 690mb's (I know - not feel related) - is perfect. I'm sticking w/ the Titleist. I wish the 33's didn't create so much spin - b/c they are very soft.
