Remembered that I didn't actually get a chance to load up the game yesterday like I thought I had after I downloaded a some mods so I dragged them out and was able to load up the game (with MFR in). \o/Yeah, disabling the mod still loads it, but it doesn't crash.
And the only way I know how to change the forge version is in the MC launcher.
Now I'm in the process of narrowing down the culprit...
