Reba's are one notch below Sid's so pretty high up the range, weight is approx 4lb IIRC (info should be on Sram's site)
XC/Trail range goes Dart, Tora, Recon, Revelation, Pike, Reba, Sid
Very good forks, highly recommended I used to have a pair, but sold the bike they were on so sold the forks as well.
