If cost was not a concern, what would you recommend is the best material (durable, high quality) to use for Water Resistive Barrier on top of Plywood? I have heard mixed reviews on Zip Systems as something production builders use since it's easy to install but don't know which type of material is good? E.g. Asphalt felt, Plastic houewrap, Liquid-applied WRB, Rigid Foam, Delta Dry etc.

Thanks Mike! I'm still in the design phase. Hasn't started constructionyet. I read the article you referenced, very insightful. Also watched the viedeo. So would you say Plywood + Peel and sticks (Vent SA from Cosella-Dörken) is the best way to go for optimal outcome? Any tips on which materials to use? Plywood thickness, tape or fluid-applied gun, which brand?
