They had a model design change from the original conception. When I first ordered it last summer there apparently was some issues with the design at that time. When I spoke to Len he mentioned that there was some concern as to its durability. They went back to the drawing board and came out with the design in its current look. That's why I didn't receive it until about a month ago.
Like you, I love the idea of a "standalone rest", no strings, but it will also have to work well too. Once I get it on the bow and start shooting some arrows (I'll be using aluminumand carbon)through it I'll let you guys know how it does for me. But I'll have to post that in the
Bowhunting Gear Review forum and not here LMAO
