I have been riding the Decade 139 and Decade binders for some time now, and I must say, I am very impressed. The stability through the wake is similar to the Natural, but the speed it carries is unreal. Edge to Edge responsiveness is a little slower than the natural due to the rolled edge, but definitely picks up plenty of speed into the wake. The board finless is plenty grippy for me, so I have not tried it with the fins on. If anyone has ridden it with the fins, let me know what you think.
The Decade Bindings are super comfortable and do not break down. I have been riding the same setup since September and I haven't noticed the bindings loosening up at all. When I first got them, I let the binders sit in the sun for about 3-4 hours until they were nice an warm before sticking them on my feet. They seemed to pack out just enough to give me a snug but not overly loose feel.
If you like a stiffer boot, try the vice, but I am content with the decade for sure.
