i used to ride it. put a wide ruler on top of seat from high end of nose to the high end of tail, covering the whole length of the saddle. put the bike on level surface. put level on top of the ruler on top of saddle and make it completely level, nose to tail. ride. if you slide into the dip then nose up 1 degree (use the precise angle measuring device!) if you have pressure in "sensitive" areas then nose down 1-2 degrees. This pretty much applies to all mainstream saddles on sale today. I used Fizik Aliante, Arione, Gobi, S/I Flite and now Selle SMP. Same rules apply. Level from nose to tail. Then ~1-2 degrees nose down or nose up if required. Simple. Aliante sometimes "looks" as if it's nose up, dont trust your eyes, use the level.
