I’ve not got this particular one, but I have an RL2 McQueen which I think is pretty similar (34mm stanchions, RL2 damper) and it’s fine. I’m not a fork expert, but I’ve not noticed the forks, which is a good thing.
I’ve also got the roughcut damper in some other forks, which has noticeably better damping; those forks are really nice.
And I’ve got some much older RL2 Slide forks (32mm stanchions). I think they’re a bit flexy, and I’ve definitely noticed them just sort of giving up on big rocky descents. They’re currently sat in the shed waiting for inspiration.
(I’ve kind of decided to stick with X-fusion forks since I more-or-less know how to service them myself now, and I can’t be bothered to figure out how to service other manufacturer’s forks as I’d rather be doing other things).
I think the Slants have 34mm stanchions? If so, they’re probably a good deal better than Rebas.
