Best drive gear ratio

Is there a good way to choose a gear ratio for our team’s drive? We want it to be pretty fast, but still able to strafe left and right.

From what I’ve learned with X drives is past high speed motors and 4in omni wheels, it tends to burn out. 3.25 in Omnis with direct high speed will be your safest bet

What weight range does it work with?

With the 4in, 15-17 is the max until you start tripping motors. I’ve never hit a max with the 3.25 wheels however
