They are definitely an awesome find, but I'd probably use two per stand as I prefer more dynamic basing than WarMaster conventions usually allow.
For example, I base 9 Cavalry models for light/medium and 10 for heavy. Infantry depends on how easy the strips are to modify, but monsters I typically base 2 per stand. I typically individually base the left-overs a la Blacksmith(Javier) or make extra units.
As I mostly paint and seldom play, I have been toying with the idea of creating my own basing system, to play both WM, WotR and Impetus. I just haven't found a system I like yet.
