I absolutely LOVE the Vesrah RJLs, and those are the "cheaper" pads (if you can call $90/set "cheap"). Their premier pads, SRJLs, run $150/set, and are widely considered to be as good as the reknowned HRC pads, if not better. Here is how my Vesrah distributor describes the two:
"RJL: harder backing plate and more initial bite than sintered metal pads
-- great for the racer on a budget as well as most trackday riders.
SRJL: linear feel, the more you pull the lever, the more bite - you will probably scare yourself silly the first time you use these pads, they bring the bike to a halt RIGHT NOW! Don't buy these unless you are ready to spend $150 for pads from now on because you will not be able to settle for anything else in the future! You have been warned..."
What I cannot tell you is whether either of these pads are suitable for street use. All of the people I know running these pads are fellow racers. For street use, I think EBC HH pads represent a good compromise in performance and streetability.
