One of my Ork units I do like are my Stormboyz (even despite Simon calling them the Lipstick Boyz) however they are leaderless, until now!
Games Workshop do produce a Stormboyz Nob, however it is only available by mail order and not from their shops.
So when I was up in Nottingham recently I did get the Stormboyz Nob when I visited Warhammer World.
It is a nice model and will certainly give my Stormboyz mob a bit more punch.
