I run a Z950 with a 60" MOD. It has more than enough power for the MOD, but yea, more is always better for mulching, no doubt.
The MOD is far better with OEM wavy mulching blades than it is with the std high lifts for all around cutting. Several of us here run our MOD's like that and have been quite happy with them set up that way.
