i think a cranked watts is a bit of an overkill at the moment as mine runs the same suspension setup without sway bars n there is still a few mm of travel there it doesnt bind surprisingly.
as for dif conversions, if you put a LR centre next to a GQ patrol centre the rover one is dwarfed. Plus the cost and availablity of replacement parts for the patrol difs is much better and they are overall much stronger. I would love to chuck some GU difs under my disco!
good to hear the car drives straight!
