Osage? See it alot. I beleive this is a wood? Or type of shape?

What are proper woods? I seen longbows listed as hickory or oak, Figured woods like these wouldn't have a nice flex or smooth draw.

Backedbow? Think I got this, but definately appears a bamboo backed 50# somtimes can surpass performance of say 60# pure wood bow.

Some longbows do not have a riser cutout or rest. Some do? Do people just shoot off thier fingers?

Do these bows lose any flex or poundage over time? Pure one piece wood selfbow or backedbow? I would tend to figure backedbow wouldn't.
