How to Determine What Offensive Sets to Use?

Any advice on:
(1) How many different offensive sets should I focus on? Right now I generally pick 2-3 sets, with about 33% to 50% for any given set.
(2) I know there is a description of what each offensive set is about, but what do you look at to determine what sets to use? Trying to figure out, what sets to pick - motion, high post, princeton, triangle, five out, etc. What do you look at to determine what sets for your team to use in any given season, etc.?
Any advice is welcome and appreciated.
