Once again....
What I quickly discovered when I re-entered the current Trad world is about the time you think you are really Trad because you are hunting in buckskins and leather with a top end custom recurve and woodies, there's some guy hunting buck naked with an original plains indian stick bow and hand knapped flints who considers you a clothes wearing hi-tech pantywaist. :D
So being I figure the only person I have to satisfy in this regard is myself. As my signature says, I'm as Trad as I wanna be.
Roughly 60% of my archery time is spent shooting/hunting with one of my recurves. The remaining 40% of my archery time I shoot one of a couple compounds I have set up for barebow/fingers, or one of a couple I have that are shot sights/release. Doesn't make me any less Trad when I'm using a recurve, and I'm rather pleased that I can shoot well in three entirely different archery styles.
So once again for the record; as far as I'm concerned, Trad is one string with no wheels, eccentrics, etc. (no, I don't think Oneida bows are Trad, before someone brings them up). IMO it's irrelevant what the riser/limbs are made of as long as the bow is a single stringed recurve, longbow, or permutation thereof, drawn & released by hand (or thumb ring).
What about sights? Back in the 60's-70's, most of us used some form of simple pin sight on our recurves. I still have original Bear recurve sights in my cache. That was a basic part of Trad then, so it must be now, too.
As for arrows & fletchings; carbon, alums, woodies, feathers or vanes, it's all good as far as I'm concerned.
Broadheads; from a purely practical standpoint it's aximomatic that cut on contacts work best with the relatively low KE of Trad, but if you shoot replacable blades and have enough buck to make em' work, more power to ya...
