I finished the Shootaboyz tonight and man that got tedious near the end. I had to force myself to finish! But after a shot of Dul-Cote I'm quite happy.
So I've now refurbished and re-based all my Lootas and 2 units of Shootaboyz. I don't have any plans to re-paint anything else as a new Kulture and since I only play one I don't think it's much of an issue. Of the models I have in my current list the Gorkanaut, the mek gunz and the planes have clan paint jobs that aren't Bad Moonz.
The other lootas and shootaboyz are not klan specific.
On a side note these Boyz use to be slugga boyz but were converted to shootas in October 2012.
