I'm remodeling in climate zone 1. We already pulled off the old siding and damaged felt and wrapped the house in tyvek homewrap (not stuccowrap or drainwrap unfortuntaly). Originally we were going to do a layer of felt and then lathe and three coat stucco. I've recently learned about the benefit of having a drainage plane. I dont think I can afford the delta dry prodcut. I as thinking of going with a layer of obdyke hydrogap, then 60min paper, then lathe and stucco. Does this seem like a good cost/benefit for my situation? Would people recommend a different solution? thanks!

Not sure if you found your answer yet, but, regardless, you might want to check out Matt Risinger. He's a builder based in Austin, TX. He has some fantastic videos, and is a big proponent of drainage wrap. Go back through his videos; you will find several discussing the topic.
