How do you like that insert system they’re using? Does it sit over the shaft at all? Looks interesting
That's what I need to test and what my gripe is with what is available for .166.
I have a lot (27ish?) of pierce arrows with ethics inserts that I have had since 2013ish, and like 5 have straight inserts.
I theorize/hypothesize that the hour glass portion is the weak spot on purpose; sort of like a car bumper to prevent the expensive stuff from damage. You get ~.88" I section and ~.44" overlap. They had told me .46" overlap I think so my measurements are close enough. I don't think there's enough insert in the shaft to bend. You end up with ~1.25" of outsert past the end of the carbon and I think that is far more likely to bend especially with the hour glass shape.
From my perspective, if they sold the collar portion separately, and included an extra 3 or 4 collars per dozen shafts, then it would be great. Protect the shaft and permanent insert, and the collar is easily replaceable yet (seems) strong enough to get through an animal fully intact and nearly straight on hard bone impacts.
I blitzed a truck window sized flat rock with that one shaft a few times, and only the collar was bent. I straightened it back out with some pliers and it has a small game head on it now. Being 7075, I think there isn't any chance of bone causing a failure.
I also think they should include extra o rings and whatever tool to install them. I either lost three or melted them with acetone when gluing the inserts in. My other potential concern is if there's enough precision in the (presumed) machining of the arcos insert/outsert system that they will be flawlessly free of wobble. The prototype arcos set they sent for me to hunt with looks different that what the most recent shipment that I have pictured is. I have four arrows that the shafts and insert spin flawless but then the collar isn't perfect. I can't say if it's inherent to the system, or, my assumption due to being looser than these, different tolerance for this prototype run.
If replacement collars are available by themselves, I think I will like it a lot.
