If that's cedar elm it will be very flexible and can handle the extra strain but, in my experience, it will need a backing to be safe (like sinew). I've had a couple cedar elms blow on me in areas with weak spots. The wood looked fine.... and I removed the bark when the staves were freshly cut. I'm still trying to figure out if the weak spots were caused by dry weather, fungus, or excessive strain during heat bending.
