Rca5 doesn't have the mid push of a2. It has more bottom and top though. Rc has a less drastic scoop than polished with slightly warmer highs but I have never mistaken the highs of even an unoriented rca5 for a2.
Was thinking this as well. Not clear what the midrange is like on it.
I want to keep the CC as it can work great with a bright amp (think Roland JC120), but not very flexible outside of that situation for me. Love that lower midrange growl it has though and may put in a different guitar.
