I would personally find it a very hard argument to make that we should go back to the old manufacturing methods.
I am not saying or implying such. I do believe the debate is that there are some, even many, who believe that all of today's gear is so far superior over earlier gear, that the earlier gear is now junk, maybe always was junk, definitely archaic, almost an impossibility to hunt with, once upon a time accuracy fell somewhere off the edge of the earth, they are louder than a 155, and you need a winch to pull and hold the string. Hell, according to some shooters, the prior year model is outdated.
The newer innovations dramatically reduce vibration and recoil over many, many of the older bows and that has been proven by a variety of methods from what I've read...and especially from what I've experienced.
As I said; many of today's bows need all these vibration absorbers, shock absorbers, torque controls, silencers, ported limbs, recoil pistons, etc, because a lot of what is out there today was designed to feed and quell the appetite of "zoomies" who only what to compete with Mickey Thompson on the Salt Flats.
Maybe I have always been just lucky or know how to pick a bow. I have never had a problem with all the vibration, shock, auto-torque, that apparently I was supposed to have and now requires today's bows to have all these buffer aids to make today's bows far superior to earlier bows.
