suggestions: duke, unc, northwestern?

<p>I am a rising senior in high school from Florida and have been contacted by several swimming recruiters for various colleges. Northwestern University has contacted me and has offered me a spot on their division 1 team with a 50% scholarship but I must apply ED. Duke University has contacted me and would love for me to be on their division 1 team but they do not offer athletic scholarships. The University does have merit scholarships (which provide a free education as well as a free study abroad) that I feel I am a competitive candidate for. Also UNC Chapel Hill has offered me to be on their division 3 team and they also do not have athletic scholarships but do have a merit scholarship (that provides a free education as well as a free study abroad) that I feel I am competitive candidate for.</p>

<p>Should I apply ED to Northwestern or should I decline the offer and apply to Duke, UNC Chapel Hill, and several other school regular decision?</p>
