You know, all the things that are added to a compound bow that make it as far from an actual BOW as you can make one, like.....

front sights
peep sights
drop away rests
over draws
cams
cables
string loops
"D" loops
trigger releases
32in and smaller A to A
wrist slings
Stabilizers
kisser buttons
parallel limbs
split limbs
machined aluminum and magnesium risers
50% 65% 70% 80% and even up to 99% let offs
attached quivers
etc....
I don't know about you but I don't recall long bows having any of those "bells & whistles" do you?
