Cat Skid
I used a cat skid in a mm. Worked good in powder but was not the best in trail chop but it was much lighter than stock. The one I used did not couple. Its my understanding that the one to have for mountain riding is the version that does not couple. For all purpose riding the one that does couple is prefered. Yes, I had to make drop brackets and since the Cat skid is a little bit wider than the Yamaha I had to shave the front width and build the drop brackets so they were a little offset. Good luck.
