Here are some pictures of some Perry crossbowmen I've been painting. Two of them are based as "Unloaded" markers (BELOW).
I've changed my basing scheme a bit. I now am basing all of my Piquet units on 40mm by 40mm bases. For heavy infantry-type units, I can fit 4 figures on a stand. For missile troops and open order infantry, I can fit 3 figures per stand.
This basing gives the units a better overall look. It makes the units look deeper when they're in line formation and it means I don't have to use those ugly sabot metal bases for Piquet. I never liked the single rank look of 28mm figures when all of the bases are in line.
