I just popped over to thier webpage and took a look, the knotched version look pretty good, by super expensive!
I watched the video. For those of you using one, they seem very noisey. Can you adjust them in the bush quietly?
If i let it spring all the way out it makes some noise as it hits the stopper but that is too high for me to shoot from anyway
I normally only need it a 2 or 3 notchers down.
100% its not a cheap option but I would buy it again.
