I have the V1's with the small axle nuts and never ever have I gone through as many pivot cups as I have riding these trucks (I have had them for about a year).
I think they are also slightly bent but not enough to noticeably influence my skating but enough that you can see a slight bending.
I changed out the bushings for some old thunder ones and to be honest I really like them. The look, the feel while grinding, the hight (indy are higher) and the turning (similar to an indy but it has a different effect on you wheelbase)
