Forum:Best SMG for Craw?

I recently looted a Maliwan Tsunami, level 48, from the armory. (Yeah, go figure.) I was really excited, until I shot the thing and it had a crappy RoF (2.4). Also it doesn't shoot electric at all times. So, I ended up going back to my Double Anarchy for craw fights, and my Hellfire for almost everything else. In fact, I'm so disappointed with the f'ing Tsunami, I almost want to bank the damn thing or trade it for something else. So is there a decent lightning SMG that works better for Craw? Or would I be better off sticking with the Double Anarchy? I've been looking for a better Double Anarchy, but craw doesn't seem to drop them and the one I have is pretty high end. Also this game really needs more end content. Need more stuff to do then just fight craw.
