>>1098734btw this picture should clear up the confusion about the cutouts size and purpose.
it's not about the type of pants it's about the angle of your pelvic bone on the saddle.
basically if you sit upright you don't need cutouts and for extreme aero position you also don't need cutouts as it won't change anything on a thin hard saddle.
the cutouts are important if you want a comfy seat with lot's of padding but still tend to tilt your hip forward. in this case the padding will compress into the taint area and put undue pressure and heat on it causing all kind of damage.
two solutions exist today:
1) hard saddle with little to no padding of the correct size and shape will not compress your veins and nerves.
2) cutouts on padded saddle to relieve said pressure and provide some comfort.
