I don't have these in my store, but a connected one does and I got to put hands on them. You can bend the highback backwards like you can with a Hurrithane. It's scary.
I will try to get on these soon or get an answer as to what the new approach is with the new highback.
Until then, unless someone else that actually knows what the hell they're doing has ridden them and can confirm that Burton has managed to make a seemingly softer highback ultra responsive, I suggest holding off on a purchase of the 2014's.
One a positive note, I don't think they're going to be brittle like in the past.
I sold my 2012 diodes (black /orange dots model) and purchased some 2014 diodes. Rode the 2014's and my 2011 Co2's in fresh pow at Sunpeaks couple days last week
Im a long time co2 user. My first impression in the store in twisting the 2014 highback i also thought they are softer. Having purchased, ridden, and bench tested them.. they are not.
I mounted one diode and one co2 to one of my boards just now.
Standing on the board to pin it down, i can twist the highbacks on either binding side to side about 1.5 inches. I can push highbacks directly backward about 1 inch. If anything, the new diode is slightly stiffer. The difference... New diode when you twist it at first moves easy then quickly stiffer. So its actually progressively stiffer. Where the co2 more like hard plastic..
Both bindings allow the same maximum amount of movement, but the the new diode does so on a curve.. Co2 more linear.. Hope that makes sense. Those of you who ride offroad motorcycles will know what i mean.
On my postal scale:
2014 diode- 29.68oz
2011 co2- 33.98oz
Mounted these new bindings to my banana magic 157. My size 9.5 K2 Thraxis boots fit the mediums nicely. The new helical ratchet/ladders i was particularly interested in to see how they perform, and if they fixed a long standing problem i have experienced with burton over several bindings.. Can you tighten them without the ratchet slipping a tooth? (especially the toe straps.) Yes.. It seems the ratchets engage the ladder in a more positive fashion. No slipping (yet).
After first run i decided to lean the highbacks forward a bit. Easy. The adjuster works well.
These bindings are comfortable. The top of highback does not dig into my calf. I like the ankle strap alot.. Very comfy. Toe-strap stays in place. These bindings are LIGHT.
Burton wisely did away with all the foam shit with holes.. My older diodes the snow would pack and stick to the footbed and highback like glue. (I fixed them by applying duct tape to the surfaces.)
The new diodes use a smoother surface, so no problems with caked on snow.
I like these bindings alot. Zero creaking noises from them. Time will tell as to durability.
