Hmm. Not to be argumentative but I don't see how shooting a bow without shelf or side-plate material can prove advantageous with regard to better form (an issue not directly related) or better noise control. Scuff marks that often develop on 'soft' plates and rests (but not as readily on hard/more durable bare wood), whether from from poorly-matched arrows, feather issues, etc., can actually give excellent (more visible) feedback for correcting such problems. And with regard to the 'clack' of improperly-spined shafts, that aspect will be just as detectable with or without shelf material since the cause originates from the arrow not the bow.
At least for hunting purposes I see no advantage to a bare-shelf bow except possibly for looks...which is strictly a personal (aesthetic) preference completely unrelated to performance. But, to each their own.
