If you want to build a bagged wing quickly then you may want to do it with a tubular carbon spar, like the professionals do.
It's not so easy to design an efficient planform and work out the track of the spar through the foam. It depends on the airfoil you choose. There is now a modified liftroll spreadsheet that does this. It uses an HN345SR as the airfoil, but you can easily substitute the values of your favorite. You can download this spreadsheet from the Liftroll Cookbook website. See link below. Look for "A 3-piece 132 With Tube Spar".
