Ta all.

Malakai: normally I would too, but I enjoyed the rocky, bouncy, Dukes-of-Hazzard character of Ratty's rhinos, perched on small bases. It'd suit orks well, IMO. Though I think being raised up on a layer of putty (and the extra height of the looted rhino) add to the
too-small effect.
Besides, EM4 don't do 25mm single-colour counters, and the little wagons look lost on the 31mms.

I've started thinking about cutting round bases from black plasticard, but the extra effort and potential for mucking up puts me off. In any case the wagons are okay on the rickety 22s, IMO.
For my marines I'm using and sticking the current rhino-chassis vehicles on 31mm counters (the type the deff rolla is on). They're larger than the old placcy rhinos so they fit better, but they still have more space than the wagons do, for a slightly more sensible character.

A treatise on the use of differently-sized bases for Epic vehicles. Anyone think I have too much time on my hands?
