I built up a pair of LightBicycle 65mm rims on Hope hubs, smashed one of the rims on a rock and switched to Stans Hugos ‘cos I was in a hurry.
In terms of tyre width and profile there wasn’t hugely noticeable difference between them, pretty sure the LB rims weighed less though.
I bought a spare rim from LB on their crash replacement program but only got round to building them back up when I dinged one of the Hugos hitting a rock.
I prefer the LB wheels, they do seem to have a bit more ‘spring’ than the Hugos and, hey, carbon.
Both were a doddle to setup tubeless – the LB’s will go up with a track pump with Surly Nates.
If your staying below 4″ tyres I’d look at Hugo’s too – they’re easy to tubeless and weigh not much.
