I opted for the plastic ones for this regiment but I still have the old metal models. Later on I will add those to another unit in my army.
I think I need to find some metal bases for the metal variants, I know that warmachine had some metal bases versions. I need to have a look to see if the normal 25mm circular ones also have the metal option.
No conversions on these ones because I do really like how they are.
Next update some Spider riders.
