when you realize that many archers use a point of aim system when they shoot, sights in its simplest form, then really you can't use "sights" as a measure of if a weapon is or isn't "true" because a sight system has always been used

here is the truth - you can shoow a Hoyt Gamemaster, tricked out with sights, a peep, stabilizer, SIMS stuff all over it ... and I can shoot a snakey osage bow, and we can swap ...... and both be able to shoot each others bows well. I might use your sights, you'll adapt to shooting without them .... but the way the bow works aint going to change much.

its about the full draw of the weight of the bow and also HOW the bow works (lack of pulleys, cables etc)
