I've gotten rid of my Cartel's, Flux TT, Drake DTM's and Technine Pro's all to be replaced by Union. I still have my first pair of Force (6 seasons old) on my backyard board and I've only had to replace my toe ratchets, which Union covered. They're beat but they'rs still solid.
Now I'm on the SL's, New Forces, and the Atlas. Ratchets are way upgraded on these models, asym straps are super plush (force straps are still more responsive) and the new wide split toe strap locks into both pairs of my boots, (Celsius Cirrus capped toe, and Vans Wiig box toe).
If anyone really hate's Union (just because they're anti union turds) I'd suggest a few of Burton's models (the Malavita, Cartel, Cobrasharks), The DTM's were really impressive-responsive, smooth ratchets, comfy straps. And would tell everyone to stay away from Technine, and maybe even to pass on flux (I found them rigid, clunky, and the ankle straps have this wierd loose feel).
People want real feedback, not anti brand propaganda.
I don't feel like comparisons to Drake or Technine count as they aren't really very popular for good reason. Better response than TT30's? Yeah probably, no argument there. Cartels? What year, and its been a while since they've been a bangin binding. So again, probably makes sense.
I have never knocked Union durability and never will. I'll remind you again, I've owned three pairs myself. But the toe ratchets springs break, and then they rattle all day. Does it effect the ride? No but come on, you only make bindings. That shouldn't happen.
Oh the toe strap fits your wide boxy boots? No shit. Go pick up any Burton, Ride, K2, Flow, Salomon... you'll probably have more trouble with fit than you should. Again, they only make bindings and toe straps are not that hard to design. Get if fucking together.
My anti Union attitude is purely from experience. Though I will say it was a bit strengthened by a certain brand managers shit attitude.
SL's are on my short list to ride at Loveland. So I will be using the new toe strap and the new asym strap. They have the DMCC lights to compete with, I don't have high hopes. But I've been disappointed with stuff I wanted to be awesome, and surprised by stuff I wanted to be shit.
