I rode really stiff backed Flow bindings for several years, so making the transition to the flex-y high backs took a few runs to adjust to. I ride a Never Summer Infinity-R and these bindings work well with them. I can pop, twist and jump off of everything without a hitch with this combo. I feel like my Unions give me a lot of control. I also love how well made they are in comparison to other well known binding companies. I can play all day on the hill and keep up with the boys with these bindings no problem!
