Sounds like they may use a proprietary yeast strain based on that comment. That would be the clincher in duplicating it exactly. Getting that yeast or at least knowing its properties so you can find a similar one.
I have only had switchback once. They only do draft I think. I think they are pretty small so they if you ask nice they may give you pointers if not a recipe and maybe even a pitch of yeast if you play your cards right.
Worth a shot if you really dig it. Let them know that.
