I have a single 4.7 in one of my rigs and a dual 2.28 on another. I prefer the dual 2.28 over a single 4.7 because it is much more useful. A single 4.7 is often too low (I know it doesn't sound right lol). A 2.28/4.7 would be amazing in my book. A set up like big mike is running would truly be the best of all possible options.
