Would the blades that come with the micro mulch system fit into this category? I use the micro mulch system in the fall and side discharge the rest of the time. I tried gators on top and hi-lifts on the bottom last spring and didn't notice much of a difference, so I scratched the idea of doubles. I'm always up for a way to decrease double cutting lawns. I'm running a lazer w/ 25 horse kohler.
