Been working on my Dwarves the last little bit. I was trying to think of a good way to be able to swap back and forth between using Longbeards or Warriors for my core. I decided to use a rank of 5 Warrior models to get some nice, long, putty beards to act as Longbeards. I'd use these 5 models in the front of the unit so it could be distinguished as a unit of LB rather than Warriors. I also plan to paint them slightly different than the others as well. I also magnetized the musicians and standard bearers arms so that the front rank would either be normal, shorter bearded Warriors or Longbeards with, um, longer beards. Should work out nicely I think.
