So what makes this gadget so great and how much does it cost?
Like the ZigZag does with DdRT, it eliminates the hitchcord/rope and gives a more compact setup that is very predictable and consistent... only on single rope. Unlike the ZZ, it is midline attachable very quickly and easily. On ascent, the device will let the rope just flow through it, and slack tending is easy, like the ZZ. It's two friction pins/cams are adjustable, and so far I've found it quite easy to find the sweet spot for the ropes that I have tried. The only 1/2" rope I tried was an especially fat one, and there's a bit more friction than I like, but I will try it on some others when the weather improves. The KM Max is only 11.1mm and I'm liking that rope the most, so far, but it also really seems to like the 11.5mm All Gear
Cherry Bomb and the 11.7 Yale
Aztec ropes I tried. Others have had good luck with 11.5mm Teufelberger
Tachyon and 11.7mm Donaghy's
Cougar ropes, too. It very much likes a firm rope that doesn't flatten out too much under load through the device. A few guys have been trying it with other static, kernmantle ropes like Sterling
HTP and Yale
Kernmaster for this reason.
I can tell you that compared to the Rope Wrench and hitchclimber setup I have been using for SRT, this thing tends slack better, is easier to advance up the rope on ascent, grabs more consistently and doesn't slap you in the face with a bunch of metal like the RW setup can do. The ability to quickly take it off the rope and midline attach it makes redirects and other climbing scenarios a whole lot easier. You can even set a couple of lines and travel from one to the other... just lanyard in and swap ropes. It is a very well engineered and solid feeling device... more so than anything else I've personally seen. Very comfortable on the hands, and easy on the rope.
This is the GoFundMe version, technically a prototype (but a near-production version) that was a limited run Jaime made for the first 50 contributors that gave $300 to the fund drive. Rock Exotica will produce them, under license, from here on out. They made most of the aluminum parts for this run. They will do further testing and probably refinements and handle the certification process, before they go into production and are available. No idea what RE will set the price point at, but if I had to guess, I'd say probably somewhere in the $350 to $500 range. RE doesn't make or sell cheap stuff, but they will certainly produce a product that is highly refined. This version is about as perfect as can reasonably be asked, but RE is an amazing company and will probably find a way to make it even better. It might come onto the market this year, yet... nobody knows for sure, and RE is obviously not making any promises about a release date. They'll do that when they're ready to, I'm sure... these things are always a waiting game.
The good thing about all that... at least fifty people have them in their hands, so any refinements that RE might want to make can be based on feedback from climbers putting them to work in a real world environment. That's always a good thing, in my opinion. Better to work any bugs out well in advance of any production notices. I thought Jaime's early prototypes were shear genius, and had the potential to be a better mousetrap. I really feel that his dedication to his device's development... the years of steady improvements, especially in this last year or so... has produced the best mechanical SRT device out there. Not that there aren't other good ones, I just think this one might end up being the best of the lot, at least for many people.
Of course, all of this is just my opinion. There will be plenty more video and forum post information in the coming months, I'm sure, so y'all can decide for yourselves if it is something you want or need.
