An interesting thread, because its a good example of where the trad vs. non-trad 'sides' are coming from. It seems to be mostly a matter of two issues/questions:
(1.) "When was it manufactured?" (which somehow places an invisible stamp of approval or disapproval on the item); and
(2.) "What does it do for me personally?" (which reflects our own selfish wants and expectations...i.e., not much affected by what others may think so not really debatable).
Neither of these questions seem to get at the crux of the matter, though, whether it be a bow, an arrow, bowsights, a hat, accessories, etc. A bigger question, one with more substance and more consequences because it affects not only us but the future (our kids AND our future values/traditions), might be...
(3.) "What will the kind of archery we generally prefer (call it trad) look like in the future if as individuals and a collective group we follow the course we are on now for choice of equipment?".
To me, question #3 is what makes my own view of 'What is traditional?' lean more towards a conservative approach. If we each don't make some common-sense lines in the sand for where we are personally going with trad and where we WANT the sport to go, in the not-so-distant future the idea of hunting in a traditional mode may be little different than what we see in modern bowhunting or target archery supply magazines now. And whether that equipment setup has 'wheels' or not (not having wheels has somehow become the Holy Grail of trad...not exactly sure why) won't make much difference because everything else about the setup will look like a Chuck Adams commercial. I'd hate to see that...to see the basic identity of this aspect of archery we started with be lost because we were too obsessed on questions 1 and 2 to see the forest for the trees.
Anyway, thats why my own opinion leans heavily towards recognizing that the term 'traditional' does have real value and limiting choice of gear within the trad arena makes sense. In an archery /environmental sense you might say its like "going green", or in an archery / sports sense its something like staying off steroids. That sort of thing.
I know, you disagree. Well thats a surprise...
