I would say since we observe up to a 1900 cutoff date design as that is what our muzzle loading cut off date is...
I wouldn't be so concerned about the materials (hidden or not) of the bow, as I've seen plenty of fiberglass core bows at Rendezvous - and it's not the "bow" that makes the Archer - it's what the Archer can do with the bow...
IMHO, this Forum Board should be about the spirit of "primitive & traditional" bow designs prior and up to 1900... I'd give a pass on the materials as an example - a fiberglass core does not mean it will out perform an all wood bow and vise-versa... All the fiberglass does is help in the prevention of breaking limbs - it does not lend itself superior to "all wood" bows...
Just my opinion.
Remember / lamination of bows go back a far piece in history.
Joe, "It ain't the arrer, it's the Indian"....learned that the hard way, many years back, and it has yet to fail me.
I think all, or about everyone here shoots a Traditional, and wheels won't be seen.
I have 6 bows I think, 2 of them have wheels and will never be seen on this forum.
However, I will "proudly show ya" my Traditional Bows. should we ever get to that part.
I think most of you oldtimers have already seen 'em a time or three.
