My kid is sporting 10/11 M9's not the SE version though. They performed great this year, no issues. He is going to try the Flux RK 30 or SF 45 for next year as he wants to do much more park. The Flow's are a good all around binding.
All three of us are sporting Flow's
I love mine, but as I get better I do notice that they are a bit stiffer. That won't inhibit me as I'm so new to the sport it doesn't matter. But I may get a more park board with softer bindings for those park only days, We'll see...
You'll be happy with them
