I'm riding my Trek 7.4 with it's stock saddle. I've been playing around with saddle position the last several rides i.e. height, forward/backwared etc. But because of the saddle shape... if I keep it level I tend to slide forward slightly. Not too much but just enough where I find myself pushing my butt back further onto the saddle. If I tilt it up I feel like I'm sitting firm in the saddle but with the forward section tilted up slightly it pushes up against where I wish it didn't push up against.

Should I be looking at a relatively "flat" saddle, possibly one with a forward sloping nose?

I know I still have a couple of more positions to work with regarding seatpost height but I thought I'd throw this out just in case someone else may have had this same problem and found a solution.
