Rice is worth a try, but Vandy probably has better odds of merit.
An important question is, which of your extracurriculars do you hope to pursue in college, and to what extent?
Is playing D3 tennis a possibility? (Assuming you would have mentioned if D1 recruitment were in the picture…?) D3 schools don’t give athletic-specific scholarships, but being an athlete they want can improve your prospects admissions and/or merit-wise.
How about music? Is marching band something you want to continue? Other types of ensembles? Conservatory-level music instruction?
There are a lot of good schools out there for math/econ and Spanish, so these other parameters would help to bring recommendations into focus.
