I don’t think it will look strange but you probably don’t want to take both. If you are willing to start early and if you plan to prep a lot then I would go for the old SAT. For people who plan to kind of wing it and not study, there is probably an advantage to taking the new SAT since it will be a little more of an even playing field when it first comes out. But if you plan to do a lot of prep then yes, there are a lot of resources and you know exactly what you are preparing for. So I would probably go with the old test given what you indicated above.
