You're correct about Raiden bindings not having canted footbeds. I think it differs between people, but personally I didn't notice any pros or cons with the canted beds when I used the wedgie on my deltas. Unless you have pain from stress in your knees, I think you'll be fine without canting. My Raiden bindings are much more comfortable than my Ride's were (it might differ by model though). I feel like the ankle and toe straps are much more comfortable and the highback has a more "natural shape" (couldn't even fold the highback all the way down on the Ride bindings because they were too wide at the end). All this is just my opinion though. Other people might have different experiences.
