I think you should try and identify a possible career path post-pharmD. If you know what area of pharmacy in which you would like to practice, then you can narrow the list of schools by focusing on the ones which are more likely to develop your skills accordingly and grant you the opportunities to get into the area you want. For example, if you are interested in working in the pharmaceutical industry, there are a handful of schools (e.g. USP, Rutgers, etc) which have very strong ties with the industry and frequent opportunities to network in that community.
To do this, I recommend trying to make contacts with pharmacists working in all the areas of pharmacy - community, clinical, academia, FDA, military, industry, managed care, etc. Speak with them about their jobs, the pluses and minuses.
If you are still unable to narrow down the list of possible career choices, then you should choose a school that gives you a LOT of possibilities. And that should also narrow your choice because most schools cannot truly do that to the same degree they can for specific avenues.
Remember, a PharmD is not the goal - it is a means to your goal which is a specific career. Tailor your choice towards the school whose program will help you most in securing your goals.
