Moom Issue

Every project has some kind of unforeseen issue pop up at some point (or at least it seems so for me) and I've just hit my first one. I have been using the Moom rig as my character, and after finishing the props for him I have noticed something about the rig. The arms aren't both FK or IK, they're one of each! It doesn't seem so bad however I can't stand using one of each, I know that when it comes to actually animating properly it's going to piss me off rotten. I have been looking around on the web to see if there is anyway to combat the issue, but I haven't found anything.

So, I'm downgrading. I'm still using a Moom rig, but it is an older version which doesn't have all the lovely capabilities of the newer rig. However both arms use IK's.
