Spars in a skinned foam core wing

I am about to get into foam core wings, building a vacuum system now (http://www.joewoodworker.com/veneering/EVS/concept.htm), and I am trying to get an idea of how i want to lay up my first wings. I see a lot of build photos and logs, but I am having a hard time deciding on what kind of layup and spars are best for what. My first wing will be for a %125 slipso (http://www.rcgroups.com/forums/showthread.php?t=418625) and my second I want to be a simple high aspect flying wing(a simple multibumm). Is there any information of spars and layup options?

Thanks
Ryan

Whoops meant to post on another thread.

Plan on bagging multiple parts before you get it worked out but generaly Lay the skin on bias and through some carbon unidirectional top and bottom for spar caps and the foam core will act as the shear web. Uh I think, Lee

This may be of interest.I'm about to start my first foam wing and I'll be using Verns method.
