The wheelbase is the same as the Flowmaster, it's got a 20" long deck. It might be a couple millimeters longer since it has a more slack headtube, but that won't matter much. I'm coming from an Ultra Pro so it's easier for front wheel stuff because of the steeper headtube and it took a little to get used to for manuals because of the longer deck/wheelbase/steeper headtube. Definitely is dialed though.What's the wheelbase on the freeflow? And is that a 4.5 deck plate or 5.0? How does it feel balance-wise for hang-5's and manuals compared to an Old A/Old B?
