a 9-mile ride isn't enough to tell you anything about either the saddle, or the shorts.

the seat & shorts going together or not is pretty simple to figure out -- one is either too big or too little for the other. some chamois are really small & narrow, so a switch to a wider seat might make a short unbearable because there isn't anything between you & the saddle.

take your pick as to which part of the puzzle you want to fix first, shorts or saddle. and just because some think a short is great, doesn't mean it will work for you. you need to find your own faves, and only riding in them will tell.
