What rules are you planning use with them?
None in particular : I'm not much of a gamer but I like my units to be compatible with the most popular rules set, in this particular case Black Powder or something of the sort. I prefer to base my figures in stands of three to six castings rather than individually, hence my taste for larger units which look better in my mind. I know many popular current rules sets call for figures to be mounted individually on small round bases but that has never had much appeal to me.
