Im at 199lbs and I have settled on Riptide Krank 93a after sanding down the bottom barrel bushing to 10mm.
sand down the side with the sharp edge (open end of mould side) and have that face your hanger.
I was wheel biting with Ace Hards, put wheel wells on the board I was on, and still got wheelbite!
52mm f4 classics or conicals, 52mm dragons for shite ground.
Then I went through bushing madness:
Indy Black aftermarket 94a (way softer than Riptide Krank 93a) but they were much cheaper so I gave it a punt.
I was thinking to try the 96a yellows, but im not into yellow bushings
Riptide APS 95a (felt stiff and didn't feel very responsive) they could have worked just didn't turn deep enough
Riptide Krank 96a (worked, but decreased the turning radius of the truck, maybe for big peeps or those that want to see if 56mm and up will work)
Riptide Krank 93a bottom 96a top, I liked this combo, might go back to it.
Bones Hard, kinda worked, but for me it just turned into a harder to turn truck, and I can go to another truck brand for that.
Riptide bushings seems to be harder than other brands, or maybe they are just more accurate in their duro rating?
I also put in riptide pivot cups halfway through the bushing changes, all I can say is they are GREEN......
Im on a FA/Hockey original shape 8.18 with DIY wheel wells, I think I can easily go to 54mm and still not wheelbite.
Now the trucks will still turn and feel like the stock bushings, and ACE hard bushings, but I just don't wheelbite.
Hope this helps.
