I went with the 5-15 range. I don't appreciate the small scale of plots and the narrowness of PC capability associated with low levels. I also feel that I can acheive the sort of world shaking plot I like in levels 10-15, but feel that beyond that, you are just making the same task less manageable with bigger numbers, more attacks, and more PC capability but not really expanding my horizons for the type of plots I want to run any further.
