Maybe I over simplified the whole idea too much, but so far this is what I've been using. I may go to a slightly longer arrow shaft (this one is only 2.25"), but using fairly short tree straps (4') I'll probably never have to use a Marlin Spike Hitch. Anyone see anything wrong with this? I like it because the Whoopie's adjust very easily and it's very simple to use.
In case anyone's wondering what the black is on the arrow shaft, it's a ring of narrow tape from something I was working on and changed my mind... never took it off.
As we say in these parts, that's the Shishnizel! Simple, light, provides for whoopie adjustment, eliminates all but one piece of hardware (the toggle), this is it for me.
