For a basher 60/40(either way) is likely not that relevant. For a racer i guess i could mean a small lap time advantage in the right circumstances.
Very slightly forward should be great for bashing. The handling should be quite neutral and better than the original Flux which i had no probs driving anyway. I've never seen a balance test on the original but i would have to assume it would be a bit rearward just from the layout.
Being center balanced certainly didn't hurt
