I have a self bow, but I don't shoot it much. I'm really partial to my laminated longbows, but I shoot wood arrows pretty much exclusively, and I use either a side quiver or a bow quiver, depending on what I'm doing or hunting. I don't know where all that puts me on the 'traditional' scale.
Where would G. Fred, the Wensels, or even Fred Bear fall on the scale, since they don't or didn't use back quivers or selfbows. I think Fred Bear used fiberglass arrows quite a bit, too.
Just my humble opinion, but I think that 'traditional' is pretty much a bow without wheels. Lots of folks have been using bow quivers and shot other types of shafts besides woods, and I would think that most of us on this site are pretty traditional in mindset, but may not shoot selfbows, wood shafts, knapped heads, etc. I did get to throw an atlatl yesterday; now that's traditional!
