I started a post on this rest a few months ago. Was just about to buy it, but spent my money elsewhere
It still seems like a nice idea. The one thing I don' t like about it is that I don' t think you can fine tune " when" the rest drops, as you can " to a degree" with other cable driven drop-aways. This can be important to some Solo-Cam bows that require a little longer support.
Also its a bit more on the complicated side compared to a shakey or TKO.
otherwise it may be a very good rest - hopefully someone will give a report
