Indeed, I do tend to do that quite often I'll admit. The ZK2 really backs those claims up for me though. The ZK1 was already a great tool, it had some drawbacks, like it's all steel construction(had to watch that while tending your hitch, more than a few of us Rw users knocked ourself in the mouth with it and learned that the hard way:/) and how it could jam the hitch sometimes while tending, those large bolts and nuts sticking out on the sides. The ZK2 and rigid tether fixed the majority of those problems though. It's aluminum now, instead of steel. The rigid tether fixes any jamming issues and makes it all run smoother in general. The built in sheave cuts down on friction and further adds to the smoothness. The cut out middle makes for a great place to clip in a tending carabiner. The sexy star head, rounded screws make it sleek. I can't really think of any thing more to improve it. For me, the RW in general did what the Wraptor did for a lot of climbers out there, it made me a vastly better climber and greatly improved production, while making the physical aspects of climbing a lot easier. The ZK2 is basically the culmination of a vast number of climbers inputs from around the world who used the ZK1 and other prototypes Kevin made and tested. I'm sure Kevin will think of ways to improve it, but I'm not inventive enough to think of how to improve upon this product, so to me it just seems perfect.
