I use Ride CAD. This is one of most stiff binders on the market.
Here's the list of another one:
Nidecker act carbon (pro 900)
Ride Spi (highback aint that stiff as CAD)
Catek FR2 (deserves to check out, but don't buy this - they'd kill your lotus).
may be something else, i don't know.
I'm personaly very happy with canting base on my CADs(i got two pairs btw). this was on NRC also. This is the greatest thing about the bindings.
