Truggy Weight balance, should it really be 50/50? What's best

[Finnster]

I was finishing up on my Hyper ST conversion and I was mounting the batt tray I made. I was using a balance to figure out the weight balance, and was suprized just how forward I had to push the batt to make F and R reasonably balanced. basically I could shove the batt all the way to the str rack and the R was still 100g heavier.

I didn't like it that far forward, so I moved it back some, but def biased to the F. Looking at my Revo, it was def R heavy as well.

How much does it really matter.Is 50/50 balance even optimal, or should 40/60 be better. Too much weight on F may make it slow to turn. What do others do, and have you noticed a big effect?
