We put as much mass down low over the back half of the robot including the battery, 2 AM shifters, 4 CIMs and every bit of electronics we could squeeze in there. The ball collector/ejector was in the front between the front two wheels so it was very light in the front. The result was a dropped center 6WD with very little rock. We were driving on the back 4 wheels 99% of the time which made driving more “predictable”. Basically the front wheels were only in play when we were on the ramps. The whole thing worked great and the drivers didn’t complain about any annoying rocking that I remember. Point is design for what you want depending on the game.

Oh, I didn't mean that you always want center off mass over the center wheels. Yours is a perfect example of when you'd want weight towards the back.
