That Batman is awesome, very nicely done!

I know what you mean when talking about the type of plastic. A good point of comparison would be the MU figure's grade of plastic versus the Captain America movie series.
Posing an MU figure is easy and they tend to hold position, mostly due to the grade of plastic. The Cap figures were "bendy" and don't hold poses well as the plastic feels less substantial and a bit cheaper.
By the sounds of it Marauder use the better grade (ie tougher, less bendable) of plastic but i'll let you know.
