I wonder if it's much different than a 5150+ with 5 fin boxes? My 5150+ tail is narrower than my 2win tail. The 2win is 5'8 and 5150+ is 6'3. It felt kinda weird running it as a quad, but waves were small and weak so I couldn't get much drive out of it and not much face to work with. It paddles great though. I debated running it as a 2+1 instead, but I was like I'll just get used to it so when I return to norcal it's not a big surprise in more critical surf. Keep in mind the 5150 doesn't have much concave if any. Most of my stretch boards have double to single or just a deep single. I think it takes some getting used to.
