I really sympathize with both sides of this argument. Since I spend all day every day with new and old traditional archers I'd like to weigh in on this topic. More than anything to hopefully persuade some of you guys to have a little compassion for those who are less experienced. Pointed advice is needed, and generalities don't make sense to a guy with no experience.
This thread is great advice for the experienced archer that has gone down the path of over analyzing the sport. But not for the beginner full of excitement about archery, without a lick of experience or knowledge to fall back on. There is something to be said for not complicating this sport. But there is also some advice that will only further frustrate a lot of beginning archers.
It is simple to you guys that have done this since 1950. You have a lifetime of experience behind you. If you have experience under your belt then you know tuning either through reasoning it out, or just a "feel" you have developed. You probably also have a trash can full of tester arrows that can help you identify the correct shaft. You can grab some arrows and find what flies perfect. Not everybody has that.
It is not simple to the guy that bought a Samick Sage from the Big Box store and they sold him a set of .300 spine carbon arrows to go with it. He is scratching his head and watching his arrows wag their way down to the target. The "KISS" method, or the "grab a set of arrows and go hunt" method, doesn't do this new shooter any favors. He has, literally, no experience to fall back on.
I don't necessarily like the new age, ultra technical line of thinking. I'm relatively young, but traditional archery has literally been my lifestyle since I can remember, and now it is my livelihood. I find myself far more inline with you "old school" guys. Just last year my cousin built me a bow and brought it to Texas for a pig hunt, I brought some woodies that I "thought" should work out of the bow. The first day I had that bow in my hands I stalked and killed two pigs. The bow had a different impact point than the one I was currently shooting, and my arrows hit to the left. My arrows weren't "PERFECT", but they were danged close. I was able to make a mental adjustment after a couple dozen shots, and my arrows zipped through both sides of both pigs, both fell within sight. No tuning required, thankfully I had the experience and a trashcan full of old arrows to choose from.
The guy that over complicates this sport leads himself down a path of constant frustration and a loss of confidence (the opposite of what he's striving for). That guy needs to understand that this sport is simpler. I sometimes feel frustrated when the conversation turns far more technical than it needs to, and I want to smack some of my friends on the head once in a while and tell them that it is a lot more simple than they are making it (all in good fun). These guys need the KISS advice.
There is nothing wrong with understanding the basics of how and why an arrow flies out of a bow. What does a stiff arrow do? What does a weak arrow do? How can you identify a stiff/weak arrow, and then how do you make a change to that arrow to get it to fly well? The pursuit of this knowledge is not sacrilege.
As bowhunters, we need to strive for an arrow that flies true. No fishtailing, and no porpoising. Arrows that "group", but porpoise, are not tuned.
There is a happy medium between simplicity and understanding the physics. Personally that is the medium I strive for. I am happy to talk the technical talk, or simply grab a set of arrows and shoot.
This forum is an excellent resource. This sport can be as simple or as complicated as you want it to be. Some guys love tinkering, love to experiment with tuning methods, arrow shafts, point weights, FOC, etc etc, and they LOVE the pursuit of more knowledge. Some guys want to just watch their arrows fly without the fuss. Both guys love archery. Like I said at the beginning, I enjoy both guys, and depending on the day, I am both guys. There are more than one ways to skin this cat.
It is not my intent to offend or cause conflict here. Great discussion.
