Over the years I've used…
Thomson (superb quality, found that there was a little flex though)
RaceFace Deus (fish didn't last long but light)
RaceFace Atlas (lovely, but didn't feel as well finished as the thomson for same £s)
Sunline AM (bit chunky, but super stiff and strong, seems V well made… currently on the 7" bike)
Sunline XC (absolutely beautiful – I'd rate it higher than a thomson, which is most peoples standard…. currently on the 4.5" trail/xc bike)
There'e been other cheaper ones… DMR seem really good value and worth a mention. Got a Ritchey WCS on the road bike, but bolts round quite easy).
Seen the Nukeproofs and look like Thomson quality, nice… wouldn't complain if I got a bike with one on.
Reckon Sunline would be my best recommendation these days though.
