Scale size, which is better?

Big scales are touchy, because of all the cross the newer karts take. That's what I've found. Need to make sure kart stays centered on the pads where the sensors are located.
Id agree with the post above, i wouldnt want the pads to be any bigger than neccesary, to make it as accurate as possible and easy to keep the kart centered on the scales.
Bigger ones make it easier to scale with out having the kart roll off. I seem to get the same numbers small pads or big pads. I've got the bigger ones just from racing cars before I got into karting
