I really like them, I have them on both my bikes now. The 26in rim weighs 598g (weighed them myself) and I'd say are as strong a Atomlab Pimps which weight something like 740g. I used to have pimps and was always trueing them and even put a flat spot in one. I only trued my one set so far after a full season of riding.
I've only rode them like twice so far, but they seem strong. People said they're really flexy but I haven't noticed at all. I wouldn't trust them for everyday dirtjumping use though. I don't think they could handle nose cases or ejects when the bike goes flying. And I don't know about footjams either.. I actually really like the Reba so far though!
Ya, apparently the arch on the reba is stronger than an Argyles. It's hard too actually jam though cause the arch is so close to the tire and it's thin, so your foot sorta just rolls over the arch. I'm not pro at them though so that could also be why.
argyle at 80mm = reba at 98mm
argyle at stock 100mm = this reba at 118mm travel (2mm from stock)
