Hey guys, thanks for the comments.
All I'll say about Arjac is that his hammer looks ALOT like the shaft is made of rope. I've noticed it on alomost all the Arjacs I've seen in the flesh too, so before you start painting make sure you try and straighten that up.
Yeah, I've tried a couple of times to straighten it out with boiling water, but it just keeps warping and twisting back when it cools. I have the same problem with the Emperor's champion's sword. Never have this problem with the FW resin. I think I'll steer clear of finecast as much as possible in future.
