Compare with 4WD 1/10 EP, is the 1/12 diff generally losse than 4WD 1/10 EP?
should be close. However, since touring weels are a different size, the "feeling" when turning the diff by hand will be different.
The thrust bearing should help in keeping your diff in good working order for a longer time. It should also cost you less outer diff bearings. Haven't tried one myself yet.
