I did a sinew backed ERC molle once. It shot well. But I learned one thing. Run a layer of Aimee up the levers. This one was mostly heart wood. It had a good profile when braces before sinew backing. After backing and bracing for te first time after, the levers were flexing a LOT. And they were roughed out almost 1” thick. If I was thinking I would’ve just used a shin of a dense stiff material like black locust, bamboo or something of the sort in the middle of the lever. But I used a splint of black cherry deon the center, one on each side and one down the belly of the lever to stiffen it. I wasn’t thinking that black cherry wasn’t much stiffer than the ERC.
Essentially what I’m getting at. Stiffen the levers, or theyll be flexing. But it does make for a nice shooting low mass bow.
