There is lots of good info so far, I am the same age, height and weight (within 5 pounds) of you. I can sit on just about any saddle at this point as long as the position relative to the bars is correct. Out of my 5 bikes I have brooks on 4 of the 5 and it's all about the pitch of the front or me, plus height over the pedals. I did have the issue of the saddle being too high when I had platform shoes versus clipless (with clipless needing to lower the saddle .25 to .50 inches in my case. I would first try to put the seat what "feels like" a little low then ride again, if you still have the pain adjust the nose of the saddle down until the pain goes away; you may feel a little extra weight on your hands/arms when you do this. Once the pain goes away, you can adjust and try again. Good luck!!
