Fish or Classic Longboard

Hey everyone. I have the option to get a sweet retro twin keel fish or a retro single fin nose rider longboard. I would get to help shape it because i know the shaper really well (and a good price too). I just have to decide between which. I already have a longboard and a short board, but my longboard is kind of a crappy nose rider and my short board doesn't hold well in overhead surf. Which one do you think i should get? By the way I'm 16 and on my high school surf team and i am very experienced, so this is no matter of learning, just stoke!
