Thanks Tom,
It doesn't appear that trying the Alfa Free on for size will happen anytime soon in my area, but we'll see.
My Switchbacks also have problems locking into place in freezing weather. A small layer of ice forms under the cross bar and it doesn't take much to keep the toe from locking down. I often have to clear the ice with a scraper. I usually apply some glide wax to that area before I head out, but it doesn't always help. That is my one complaint with the system.
Yes, I know about the problem you describe above and do the same with some paste wax. The current issue is that the hooks that come out from the riser and hold down the bar when you flip the switch won't extend. It must be an internal freezing problem because bringing them inside overnight alleviates it. The switch has no tension to it when frozen, but snaps into place and the hooks extend when warm. I haven't torn it apart yet to see whats going on inside.
The new Xplore / Free system is a step up in control over the typical soft leather boots, but it is still a passive system, and I think many people who like the active feel of the spring cartridges, would probably miss that feature. I'm hoping that the hard flexor, when it becomes available, will help in that regard, but it may not be enough for many.
I started telemarking back in the late 70's well before cables and don't really need them to initiate a turn, but they are of course necessary on the Switchback to hold the boot in the binding. I LOVE the free pivot of the Voile, which is why I put up with the weight! The XPlore system looks very interesting to me! Looking forward to more reviews as people early adopt!
