The Flux PR use to be called the PR15 but this year they added some of the tech from the discontinued SE30 making it a really good binding in the low price range.
Flex: Medium bordering on soft and it’s got a pretty solid flex for a binding of this price.
Adjustability: This is one of the only flux bindings that doesn’t have a tooless adjustment system on the top. Normally Flux bindings have a toe and heel ramp but this only has an adjustable toe ramp.
Comfort: Pretty comfortable for a binding of this price range.
Heel-Toe Response: Kind of like a slightly more mellow TT. It’s pretty easy edge to edge with both boards.
Tip-Tail Response: Not very buttery or pressy but most people buying these bindings will be working more on edge to edge transitioning.
Boot Support: Very supportive and it almost completely locks in your ankle.
Ratchet System: Very good ratchet system for this price.
Shock Absorption: Not much shock absorption for this binding and this is one of the only weak points. It’s somewhat damp but not a good binding for a bad landing.
So all in all this is a great binding for the price and it give you a binding that you can grow with. Yes the TT is better but this is a great choice if you are trying to shave every buck you can.
