I suggest this: take your time with each and every setup; dont jump back and forth between them, your game will suffer. If you take your time with them, youll get used to the setup and you will better see how it affects your game.
Me, I'm sticking with the MG RAd MP, MAY try the YT, but I'm wary of doing so, having adapted to the MG. I am trying new setups with it, but taking it one modification at a time, until I find the perfect blend of weight and balance to fit my game totally.
