got the mag lights today. they turned pretty smoothly at first, but got worse as time went on. had them wobbly loose and they were extremely stable (thumbs up). i think it might be due to the material of the pivot cups or the magnesium. when debris gets in there, the trucks don't jiggle. they kind of stick and you can feel it. that and maybe because of the top interlocking bushing. not bad, though. i'll try to swap out the pivot cups. slappies are smooth, but nothing to write home about, in my opinion. didn't notice the height either, which i was afraid would make the board tipsy. the main selling point is their weight, but i can't really tell once they're on the board. i think it's because i ride a small board and things aren't as spread apart, so you can feel the weight of everything. gonna shred them down, make them lighter than they already are, and throw them on a cruiser
