Couple of things. One, you do need to learn to lift yourself up onto the seat - straight up. This is the pot calling the kettle black, but I know when it's me and when it's the shorts. Two, some pads are sculpted to be thinner near the edges or have a v-shaped wedge in the middle of the back (PI 3-D, Castelli YPR03, Shebeest Shelastomer?). This is generally true in the more expensive pads (though the Descente pad from last year did not have this cutout) This will also help you clear the chamois over the saddle. Then, you can have a thick pad for the sits areas and a thin pad where the nose of the saddle will spear the short (short suck). Of course, if you are mounting aimed downhill, the lift technique is especially important as the saddle is higher than when you are on the flat and any chamois can get caught.
