Replying to Skateboarding question- Do you use the taller end of the board for the nose or tail?

I have a board with nose and tail the exact same length but the nose is slightly more curved/raised than the tail. I can ollie fine either way but im trying to decide which orientation i should stick with, (ie. should i use the nose for the tail or the tail for the tail). Do any of you jokers use the nose of the skateboard as the tail?
