i have 6x6, 12x12, 14x16, 22x24. They all get used for different purposes. i like the bigger ones for checking elevation and playing when it's windy. It's harder to learn if you don't have some visual of impact. I'll use any color that stands out but mainly use white. If i'm shooting for a group i'll pain an aiming point on the plate if not and it's just a fun day i'll paint it solid.
