If you have the means to buy RCM's Hybrid diffs, do it! The LST2 diffs are fantastic, smooth and tough as nails but it is a lot of work to make them fit. And if you break a bulkhead, you gotta do it over again. If I had a bigger RC budget, I would go for the Hybrids. I use LST2 diffs and go through the trouble of fitting them in my ERBE because I'm poor
