If you want to narrow down your list of schools from 81 down to, say, 25, a good way to do it is to make yourself a set criteria for these med schools.
You can first ask yourself, "which schools can I NOT apply to?" I don't know if you've done this yet, but see if there are residency requirements for some of these schools, or if they have a "preference" for in-state applicants. A reference book to look at is Princeton Review's Complete Book of Medical Schools 2001 edition. They list every allopathic med school, and for the majority of them provide the number of out-of-state applicants for each school, what percentage were interviewed, and what percentage of those interviewed were ultimately accepted.
Second, look at class size. I almost applied to Dartmouth until I saw that they only admitted 70 students per year. Mayo only takes 34. BU takes 136, but after the early admissions people and the early acceptance people, they only take 99 students per year from the rest of the year's applicant pool. When you consider that over 5,000 send in secondaries to BU, it can be extremely competitive. Now, I don't want to discourage you from applying to these schools, as they are all excellent (especially Mayo) medical schools. You have superior numbers to mine and I'm sure you would be competitive. But that helped to narrow down my choices, and maybe it can help to narrow down yours.
You can then look at all of the other factors about the school; pass-fail vs. A-F grading system, tuition costs, location of the med school, reputation, etc, etc.
81 schools are a bit extreme and VERY costly. Remember, it'll cost you in the four figures just for the AMCAS application. Most private schools charge between $80 to $95 for their secondaries.
