Based on the dominant foot, kicking a soccer ball, etc... I should ride regular, which is what I did my 1st season. I tried out goofy my 2nd year, and never looked back.
I think a better test is to find a smooth/slippery floor, like wood or vinyl. Run in your socks and slide somewhat sideways. See which foot you put in front, and use that as your stance. I think I read this on this forum somewhere else. Sounds like the best test to me.
