I was experiencing the same as you. Same shorts even. I researched what the "long distance" riders where using (cuz someday I wanna be a long distance rider) and this one kept popping up. I found my perfect saddle. The Selle An-atomica.

I also found that wearing bibs with a thinner chamois is the way to go for me. I had 4 pairs of PI's and have been getting rid of them slowly. The cool thing about this saddle is its adjustability. My hubby rides on one also and has his set much different from mine. We like them. Good luck.
