what opening is better for me???

personally I like to play roy lopez and petrov's allot, but i would assume to get to 1561 rating you've played some openings more than others, generally stick to what you know is usually best once you're comfy with it.
in allot of my games around 1500 mark i didn't have openings, i just made moves that looked sensible to me to learn the board rather than learning the openings.
I have a 1561 rating.what openings what you suggest me to use and tell me the moves.Thank you!
