I still have four earlier model compounds that have none of these problems. In fact, the early PSE "Pacer" (circa 1975) 60# w/50% letoff that is hanging downstairs is easy to shoot and is basically quiet.
The reason that many of today's bows have certain anti and preventive "this and that" features is not JUST because the innovation is some type of advanced idea just to improve handling and shooting over earlier bows; many of the so-called modern features are somewhat necessary to offset the downsides (shock, vibration, noise, etc,) that the radical designs and high-speed bows of today produce. It is a "Catch-22" situation.
You may shake it up however you wish. The newer innovations dramaticaly 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. Hardly a "catch-22," in my opinion.
A 60# bow with 50% letoff is easy to shoot and "basically" quiet...compared to what? The more modern bows have many superior features from the cam (vs two cams) to the dampening. I would personally find it a very hard argument to make that we should go back to the old manufacturing methods.
Your points are carefully couched in well-rounded terms, but they remain mostly subjective in nature. Most people are not sorry for buying quality.
Someone made the argument that the accessories make much of the difference...to which I would respond: apply the same guideline...do your homework, but buy the best you can afford. You'll only have to do it once.
