Vac bagged the prop with 90gm carbon on 45 Degree bias and 80 gm glass. Stiffened it considerably. That should make it quieter.
Still balances OK. In the end I made it 20x11.5 measured on the back face. Still around 12" pitch if you measure from the zero lift line of the airfoil. Mejzlik measure on the back face.
