Muzzy, I quite understand what you're saying here. However accuracy lies more in the shooter's form and release--the bow will only do as much as the shooter can.
As for zero recoil--after shooting the Guuardian for the first time, I asked myself the same question--kind of like--'what just happened'.
Guess I can relate this to, having a fish on hook and not knowing it's still there--sort of thing.Or a pill that melts in your mouth without having to swallow it whole. Almost like loosing the 'feeling'.
I think there's no one answer for your question, as this touch will always vary with the shooter.
Good topic none the less!
