A mechanical head after all is just basically a simple hinge when you get right down to it. And for me it only has to function properly as a hinge once. That being the case, I like my odds. And through about 8 different designs and many deer I haven't seen one fail or fail to open. As for the latter I don't see how it could fail to open unless I glued or tied it shut. It simply defies the laws of physics.
I use the same argument for drop away rest as well... I am a former mechanic, and now a mechanical engineer student(got tired of bein a mechanic so I went back to school)... I think I have my experience with dynamic operation
No one here can say that a mechanical head wont fail... Its simply inevitable, and I have seen there structural integrity tested in an engineering format, with one of the top 5 archery companies world wide
I had an interview with one of them and I got to see what kind of KE heads really took to deploy, and what kind of abuse a rage and other top name heads could take in test ranging from meat, to concrete blocks...
A mechanical failure is when an operation of one, or many moving parts did not operate correctly, causing an undesired result. A blade breaking off a fixed head is not a mechanical failure. It is an integrity failure certainly, but the head still performed as it was suppossed to b/c it was never able to fail in the first place b/c it is a static.
I am not a fixed head advocate, as ive stated many times I use, and will continue to use mechanical heads, but there is certainly a difference between some of your thoughts of failure and what is actual...
also, I dont care what anyone shoots
You can shoot a meat cleaver for all I care, but when someone asks a question, I am going to answer it truthfully... If i only had 60#'s of KE with low momentum, I would not use or advise use of a fairly large expandable... If you do, so be it, but if you asking, ill give an opinion.
