It's been a while but anyway. I've just gotten hold of Mansions of Madness and aim to usethe figures for morethan just the game

Just looking for some thoughts on bases for them, really...
Tempted to use Renreda's bases- the standard roundies for the smaller beasties
http://renedra.co.uk/webstore.html#Bases and the 50X50s for the bigger gribblies, but since the Shogs are on 75mm bases will this have an impact on the game itself? Perhaps drilling holes into the bases so the figures can be swapped between the 2?
I suppose at the end of the day I could just have them on the intended bases, but I thought that since they would most likely be used alongside my Black Cat Bases and RAMF figures for other games, maybe have the option to switch bases. Has anyone else done this?
