I am still of the impression that you can spend years trying to figure out which is the perfect arrow size, length, weight, weight forward etc set up, or you can slap 5" feathers on almost any arrow and go out and have fun shooting for that year.
I also agree with Orion. Almost all bows have a pretty wide range of tolerance. If it is that touchy that it doesn't, your form better be perfect with every shot or it will screw up on you then too.
Yeah, it is fun to play with our bows, and yeah, we all want our arrows flying well, but I still think we put way too much into this "simple" activity.
I am pretty certain our forefathers did not paper tune, did not weigh each knapped head, did not cut 1/4" off the length of each arrow to attain nirvana. Did not build out the shelf on the bow of adjust the nock point incessantly.
They flexed the shaft. If it felt right they built the arrow. They shot the arrow. If it flew well it went into the quiver. If not, it became firewood.
