Bad news buddy as my spare TTM-20 now has Bane's arms due to me giving the TTM-20 arms to Bane so that I could achieve the 'Boss' pose.
I already tried my spare jacket on the modified TTM-20 body and it looks great but as you say it would have been nice to have the double jointed elbows as that would have been great to use for some wicked poses, but it wasn't to be.
You can still get great looks with those arms, so no big deal
Is the zit cream taking the spots off your Bane?
