More force, if I remember correctly. using the equation F=mg(sin(angle)), and since your weight (mg) is constant, the sin(angle) changes force.

sin(0) = 0
sin(30) = 0.5
sin(45) = 0.707
sin(60) = 0.866
sin(90) = 1 (don't think you'll be going vertical)

Therefore, the greater the angle, the more force you exert.

This should be right, gotta love Physics!
