^ A lot of people like the Pro III's, but this was my experience (set em up for a retro board):
Out of the box--they don't turn, at all. Even with the nut barely hanging on. And yet, somehow they speed wobble really easily.
The bushings are too damn tall to be replaced with anything else. The only solution I found was bones mediums with the washer added to the bottom (they don't come stock with a bottom washer, there's just a seat that the bushing fit into). They actually carve decent after doing this, but still speed wobble like crazy. I got pitched and hyper-extended my knee just coming down a goddamn bank at a skatepark.
I'm pretty open minded when it comes to trucks, but these are unadulterated crap.
