Pros: Less than 6 pounds/pair, 5-16 release settings, easy to adjust, easy to free the heel
Cons: Icing of the locking plate impedes locking the heel, light for a heavy-weight AT binding, but still heavy.
Nonetheless, the Adrenaline is a pretty well thought out plate binding. It skis well, with a huge range of release settings, from DIN 5-16. Those who want leverage for fat skis will appreciate being 36mm above the ski, those who want powder sensitivity should switch to tele.
Where the Adrenaline smokes the competition is in uphill mode. It is the lightest heavyweight binding, weighing in at 5 lbs., 12 oz. for the large sized plate (less for the small). Switching to tour mode does not require stepping out of the binding, and with a minimum of practice is easy and reliable. What is not so reliable is locking 'er back down. The combination of an open cell plastic frame and metal locking plate practically guarantee snow will build up under the heel. Depending on snow conditions that snow may pack into ice, or not. If it does, you'll need to chip the ice away to lock the heel back down. The Duke and Guardian suffer from the same issue, so it isn't any worse, just something to be aware of.
It has three climbing heights, and the climbing post is easy to engage (similar to the Duke). If I were looking for a go-anywhere alpine binding the Adrenaline would beat out the Guardian for weight and easier mode switching, and equal the Duke for downhill performance.
