Agreed on the soft outdrives, but I've actually found the gear diff to be better than the ball diff on carpet. I use the desert truck diff with 35wt shock oil in it. With the ball diff, I was suffering through a high speed hairpin where the inside wheel was getting light on the exit and I was loosing a bit of drive. I put the gear diff in and although the car's steering does seem more dosile I find that you can hang onto a huge amount of speed through the corner and the traction out of the hairpin is almost like a 4wd. I'd recommend trying it, but we're not talking a huge difference, just that extra couple of %.
