mifdaddy,
One option is to not apply for Federal aid and just take any baseball and academic scholarships awarded. (What a great position to be in!) But, at the higher priced private schools, they may still require you to fill out the CSS Profile.
I wouldn't try to "tank" a year or two....but as a business owner, I understand there are things you can do during your child's junior year (this year) to help your EFC. I am not a business owner, but you may want to research it before the year is out.
