I would suggest that if you lock the front you lock the back. I had a limited slip in my rear 44. I upgraded to a lock right in the front. This made it much easier to "hop" up on stuff. But I had a near roll caused by (I like to blame my equipment rather than my own inabilities
) this combination. I was heading up a rock. Once the front came over the top it popped up a little loosing traction. The limited slip drove one tire (or the driving tire was in loose stuff) causing me to do a ballet move on one rear tire before it luckily slammed down. I thought I was scared until I looked at the guys watching me. They thought I was going turtle. The guy in front of me had a rear locker and a open front and had no issues. Softer springs and a rear locker and I can go up it like driving into my driveway.
