When I started building my Saga Viking warband, I painted up a box of plastic Gripping Beast Hirdsmen. It was only on completing them that I realised that I would never field eleven points of Heathguard! I suplemented the Hirdsmen with Metal levies and warriors from the beast, but I felt that they did not fit in well with the plastics I already had.
It was at this stage that my OCD kicked in (come on all of us wargamers are on the spectrum) and I replaced the plastic Hirdsmen with metals (the plastics are currently on ebay).
The first 2 points worth are pictured below, painted, washed and varnished with Citadel paints.
