How to change % of RB1/RB2

[ryne candy]

If I want to use my RB1 more than 50% of the time, do I move the bar to the left (showing more black, less white) or towards the right (showing more white, less black).

Move it to the left if you want to split carries with your 2nd RB.

Move it to the right if you want your 1st RB to handle everything.
