whew, that was a lot of catching up. I'm not seeing much talk about the new 550 pro4's anyone running it in this truck?

I'm thinking about getting one and trying it out and potentially putting it in a Tekno down the line on big outdoors and running my old MMP and pro4 in this truck on tight indoor clay.

I've got the exotek center chassis and running saddles inline, think I should switch back to stick or put them up front with the bigger motor?
