I really want to try out Stephen's now!
While I certainly like Sunderbruch, Scott, and Westbrook, I would say IFP has been my favorite so far. I think a lot of it is just because its so fast and flowy, can truly zip around. (Similar to if you hug the blue/green ring of Sunderbruch, just with less people in the way!)
So if Stephen's is like IFP, I am pumped to try it out!
