I used to use a bamboo longbow for a while, but only about a 55lb draw weight
Have a friends WarBow here....in the region of 120lb pull weight.
I can use it, but I'd not want to do it as a day job unless I had a LOT of training first
I suggest you get possibly the best book on the topic, which was written by an English actor - Robert Hardy - "Longbow: A Social and Military History"
I also have an replica of an older flat bow - a Mere Heath.
Make my own arrows too.
ETA: the video you linked to was interesting, but the bodkin he used was not really one designed for armour plate - He should have used one like this:
A great hobby in preparation for when we next fight the French, or the Scots
(the latter may be sooner than planned when their Independence experiment goes tits up & they head south looking for plunder...)
