As far as the original HS33s go, if you want to stay retro, I would not recommend them for anything much above 2.1 or thereabouts, unless you elect to use a different brake bridge, which is where the clearance problem lies (and they dictate how far apart you can set up the brakes, to an extent). I had to snip the second hole off mine, (same as this picture) in order to clear a 2.0 Bontrager XR1 on a wide rim.
Presumably the modern ones and aftermarket boosters don't suffer the same issues.

But they aren't fluoro.
