If there's one thing about using traditional hunting gear that often gets overlooked (or ignored) its that hunting isn't the same as target shooting. Using a simple bow and arrow to chase real live animals, on their turf and under unpredictable circumstances, is a close-range affair. Thats what works best, and thats what the true challenge of the effort is all about. Luckily, at close range even 'imperfect' bows and arrows work quite well for the task, as selfbow users can attest to. An 'adequate tune' on a critter at 12 yards might be as simple as not coming unglued...because at that range good results really IS far more dependent on the hunter than what he/she is shooting. Even though reasonable tuning of arrow to bow is of course recommended, I'll bet dimes to dollars that more bad shots on animals (wounds and misses) have been made because of 'poke and hope' shots than any other single aspect...with the possible exception of not having learned basic form to begin with.
Learn form and take close shots. IMHO, thats both the 'simple' AND the 'easy' recipe for traditional bowhunting. The rest is mostly fussin' and glitter. Not that theres anything wrong with that.
