Here's what I went with (straight from the email) per Lou's recommendation:

"Sounds the E Vap built with the heavier weight fabrics will give me the best choice for being breathable yet wind resistant. If I understand correctly we are looking at Power Shield with Power Stretch. Say the Grey Midweight Powershield with the Topaz midweight Power Stretch. Does this sound right for an outer layer on the colder days? I don't mind wearing multiple layers but want to avoid the moisture build up I get with my gortex shell."

So the jacket is made with a venting fabric the runs down the entire bottom side of the arms and then also all the way down my sides. This venting area is about 1 1/2 inches wide. I've not noticed it allowing any coolness or moisture in though. The jacket is warmer than my Gortex shell so I'm still playing with how to properly dress for each condition now. The one day I went out dressed to warmly and was moving quite a bit of sweat during the ride. The jacket worked very well at moving this moisture out. Finding something that blocked wind yet breathed well was my priority as my Gortex shell quickly becomes an umcomfortable sauna on rides. The foxwear jacket does the job admirably. Just shoot Lou an email telling him what you want in a jacket and what conditions you'll use it in and he will steer you in the right direction.
