I agree, but it does not fit on the New 3DS, so this appears to be the next best option.
I actually wish I could go back to my old 3DS for games like Monster Hunter, but Nintendo will not let you revert back down. I suspect the Circle Pad Pro XL is technically capable of interfacing with the N3DS XL, but I would have to trim away some plastic and remove buttons to make them fit together, and I am not prepared to destroy my beautiful MH4U system in a trial.
