let's say:
(close to) compass tiller, longer, stronger, longer drawlength ?
I don't see why many lams don't make a warbow... And drawweight doesn't count much, depending on the person, but I wonder if anybody would call a yew bow, with a compass tiller, 80"long, drawn to 32 inches a warbow, if it only pulled 30#...
yew wasn't available everywhere, and often elm, ash etc were used for these warbows.
warbow isn't a single type, it's a bunch of different types; laminated, selfbow, backed. And all of these make ENGLISH warbows.
but the English weren't the only tribes with 'warbows'... look at the cherokee d-bows, the sinewbacked warbows from the westcoast indians, the long, incredibly strong chinese hornbows, pulling way over 150#, the long papua bows shooting harpoonlike arrows, the small african bushman warbows, with poisoned arrows and under 50# of drawweight.
