If I where playing with my Valks like I did back when I was 13, I would rather play with a MPC. The reason is that the MPC joints are smoother. I liked changing modes in the most realistic looking way as possiable as I had my mock battle. With the MPC in Valk mode you can hold it at the intakes with your left and with two fingers your right hand can open the the feet pull the legs down and sprend them as if it's reverseing thrust. But that how I like to play. I mean, thats how I use to play.
