Oh, boy... an argument!
Just so happens this is my hot button. Let me begin by saying that modern bows are wonderful... R/D's, carbon, ILF, etc... all good and all made legal by adaptation of rules designed to enhance control of competition. None of it, neither the equipment or the competition rules, has much to do with tradition.
Traditional means to do something the same as it was done at a specific time, place or period in the past, using as close as you can to the same equipment and techniques that were in common, repeat, common, use at the time. You can always find the cutting edge example to just justify what you want to consider traditional now. For instance, you can find a breech loading rifle in use in the Revolutionary War (Ferguson)... doesn't mean a Weatherby is traditional!
If you want to think of the way we shoot today as traditional, it is, in the sense that that is the name that has been given to our style of shooting... it's a label. It opens things up to any kind and degree of modern development as long as the style is maintained, i.e. no sights. When someone offers new limbs made of molymacromarsidium a rare metalic spring material that will be discovered on Mars, that will be considered, under the rules, as traditional.
If you want to shoot traditionally, that's another story. Pick your period, do some research to see what was being shot by that time's average hunter, equip yourself as he was equipped and see if you can do as well as he did. That's shooting traditionally, as opposed to shooting traditional style.
This is the same conundrum facing muzzle loading... The traditional weapon of the frontier was a patched round ball rifle. Yes, there were exceptions, but they weren't common. The stainless steel, primer ignited, scope sighted, sabot shooting rifles in the woods in muzzle loading season today bear the same relationship to "traditional" rifles that carbon limbed ILF bows and RD bows bear to earlier bows.
It's all labels, but I like to see words keep their meaning. I have all kinds of bows, except compounds (can't hold them up, but consider them marvelous machines). I shoot them all and enjoy them, but I know in my heart which ones are traditional.
OK, the grumpy old man will go away now...........
