I have Thunder-Indy's set up on my cruiser board. Agree about the pivot cup. I took out the bottom washers too--nice and wobbly now.
The Indy baseplates make them a little higher too, which is nice. But I'm using risers, so it doesn't really matter anyway.
Pretty much just trying to salvage these Thunders that I bought a couple months ago. I went from kinda liking them, to hating them, to switching back to Indy Indy's, in just a few weeks. They're alright for cruising around though. Kind of like that quick, carvy response going down the sidewalk.
