Bro, I just got back yesterday and have been trying to find this thread to post an update a soon as possible because I was SO STOKED on how my nanner rode with my M-9s mounted to it. Now, idk if it was the nanner or the flows that was impressing me more since it was my first day ever on both but let me tell you it was hands down my best day of riding ever. 6-10inches of pow everywhere certainly helped but even still the quick in/out of the flows was a whole new experience that I was loving, and was making my buddy jealous every time he sat down to strap in. Def spend the time setting them up properly inside and you should not have any issue once on the mtn. I don't know if I just got lucky or what but I was expecting to have to take a few Green runs and a couple spills to get my bindings adjusted properly but right out of the gate they were perfect (second run was a Blue that turns into a steep Black and was still fine). I had a weird little pressure point on my front foot to the left of my pinkie toe but I think that was my boot/sock more then the binding cause I loosened the ladder a little and it was still there. My back foot however felt like it was in a glove all day and didn't need to be adjusted once. I was on gondolas most of the day so almost every run I was strapping in both feet each time but a few runs were chair lifts and I actually was able to get my back foot into the flows and get the highback up (not locked) to ride off the lift. Once off the lift i just locked the highback and was heading down well before anyone else.
And as far as the performance of the SB goes, there is a reason it is so damn popular. I'm hooked. MTX worked great on the few icy spots and the reverse camber made it super fun to butter and floated great in the one spot of knee high pow we found. I feel bad for my Nitro T1/Contraband set up. Not gonna get much love for a while.
