So I bought like 25 Giant Rats from ebay for my upcoming Skaven armies. I still need some more for my two regiments with 22 rats each, but the Doomwheel kit will have some more as well. I also bought some arms with whips. I'm going to convert my Packmasters from the Clanrat kit so all of my Skaven will be of the "new style". I'm taking suitable unarmoured rats and cut off the arms at the wrists and smoothen the connection with green stuff and filing.
