Put more bluntly: I'm trying to determine whether a Barbour Border jacket is too warm. As Badenoch points out, there are several Barbour jackets that are lighter than my Border. Unfortunately, I don't own any of them. I do have two lighter water-resistant jackets (a Filson and a cheap LL Bean rain shell). I also have a PVC Helle Hanson that can keep me dry in a hurricane (and has). That seems like overkill.
