The extra width does make things squirrely on certain trails. I run with several guys that have done it and, when we were doing Black Bear, Imogene, and other trails in that area they had a much higher pucker factor than I did. That being said, the extra width was really helpful on other obstacles, so it's a mixed bag.
Figure out what kind of wheeling you want to do and modify your rig accordingly. For me, running an ARB up front was perfect.
For those of you breaking half shafts, look into the RCV ones. Expensive as hell up front, but guaranteed for life no matter how you break them.
