Glad you found something you liked.
I find it is a good idea to have a couple of alt characters to try out new things, and redo the game, so to speak. It makes everything feel fresh.
With that said, you have to remember that you are starting the game with a veteran's knowledge. That means that all the monster will feel much easier than they would have, if you had started the game with that weapon from the get go. So, the CB is not really OP... you are :-D
