I might go a sprue of these just for bits, but honestly I'm a little disappointed. The wrong side dog-lock is a daft mistake that should have been caught, and I'm not sure 8 Knock guns per box is really playing fair...
I doubt they would mix well with the Perry/Hicks Rifles I already have, although they may look ok with Front Rank or Warlord.
That said, the overall proportions of the figures (especially the heads) has conjured up some interesting kitbash ideas with one of the WA Halfling sprues....

So far I've been pleasantly surprised by all the WA sets, but this is just a tad.... underwhelming...
