"Longbow" and "hybrid" are kinda misleading as both are what most folks consider to be a "longbow" - where the string's loops only touch the limb nocks (as opposed to a recurve).
"Classic IFAA longbows", like the straight limbed Howard Hill longbow, have that classic "D" shape when braced. Hybrid longbows show a smattering of limb tip reflex when braced.
To confuse matters more, there are "stealth hybrids" (such as the 21st Century Edge and Horne 62" Combo Hunter) that show lotsa reflex when unbraced and a classic "D" shape when braced - make no mistake, these are fast hybrid longbows!
Hmmm - if you add up both poll categories (longbow and hybrid), longbows are in the majority (so far!).
