I think you are playing the proper tees. If you are looking for a challenge, move it back a tee box, I bet you will score about the same and you will use some longer irons/hybrids into those par 4's. If you don't reach, it will test your short game by trying to get up and down.
I like to play 6800 and up, which is the back and tips at my club.
