Good Job Chief - the spring does work.
I used one when I modified my Mathews Micro rest into a dropaway a few years back and hunted with it for a few years - It doesnt make noise and will pull the rest up to the stop every time, and gives you that added support.
I also had to use it with my Solo Patriot to make the TT work. I needed the arrow up atleast 4" from full draw.
Funny thing is with my new drop zone - I only need the arrow up the last 1" of draw. I can' t figure it out.
I give up on figuring it out
