I hated metal minis.
Granted my painting has had two phases, when I was a teen and played Warhammer and metal minis were the bane of my existence (falling over, and difficult to paint). Now that I'm older and all the minis I have are from reaper Kickstarters I can't see willingly going back to metal.
Is there any reason you want to stick with metal minis? To my eye plastic and resin minis look nicer and feel more dynamic. I ask because I'm genuinely curious.
