My feedback:
Pushing 230 LB + so stopping power is fairly crucial.
Was running the Elixir CR front for about three months. Good brakes but did come across the following issues:
a. Blowing through brakes pads
b. Bleeding was a issue
c. Never could get the same feel after switching out pads. Had to do some major fine tuning.
d. Cheap design/assembly
Got a replacement front Saint and could not be happier. The ergonomics are comparable to my previous Louise FR's so this brake feels right at home.
The craftsman ship of the Shimano is far above the Avids. The caliper and lever assembly really do inspire confidence. No cut corners in the design, assembly and hardware spec.
Have been running them since October and no negative feedback yet. Have yet to come across any sort of fading as mentioned above.
As for the cost of brake pads, shop around. Online (CRC) you are looking at about $29 CAD which is right in line with all other pads.
