Been wanting the MM setup for awhile. Went 50 miles to look at another LCO's 9000(thanks, Lagniappe). So, I found a balancer on eBay for 107.50 and it was the best thing I've ever done for my Hustler Z! Took all the vibration out of the deck and I couldn't believe the change in sound and cut. My Grasshopper didn't have any vibration issues(that were noticeable), but my helper noticed the difference in cutting Bahia right off. It'll cut it at a faster speed than before. So, I ordered the 9000 today from McHenry Power in Ill. (they've been great to work with for blades, filters, clutches,etc), can't wait for it to come in!!!
