You are going to love that ride. I had a blat on the 161 last spring. Just got back from a hut trip where I should have brought my 167. I thought it was going to be a little thin at the hut and boy was I wrong. So I have yet to take a Prospector out in deep pow.
Chinese hooks versus k clips when they are brand new, not a huge difference. Once you've knocked down maybe 30 days the chinese hooks do loosen up fit wise. Then k clips should make a noticeable difference. My k clips on my sl have also loosened up though. They do not hold nearly as tight as they did. I think the new ones have adjustable tension. So make sure you get that option if you go that route.
As far as bindings go. The new Spark Tesla bindings are the real deal. Used them on the hut trip for the first time. The wide touring brackets make side hilling much more stable. Did a 7 mile skin and on a steep section I will refer to as asshole, the bars were amazing. My skier buddy went down and I was able to hold an edge with a 60lb pack on. I am sure on the Voile risers I would have also gone down. As when I looked at it I thought no way I could make it without booting.
Bringing the small brackets back up wasn't as easy as I would have liked but after several runs I think I have it figured out.
Transitioning is easy and you don't have to clean ice out of the interface like with Karakorum's. Not having pins is amazing. Will just knocked one out of the park with the simplicity and efficiency of the design.
