This is my current haircut. High slope, trimmed top.

For a normal slope, just imagine the sides has a steeper cut. It will make me looks as though I am sporting a bobcut, which will, imo, make me look like a mushroom head. :X

Different shapes of the head can carry different haircuts. What works for me, may not work for you. I advise you to visit your local barber and ask what is the best cut for you and for a professional answer between high slope and slope.
