So I've had my Brooks Flyer, the sprung B17, set pretty high for about the last 6 months.
I used these instructions from Jim Langley to set the saddle height. I thought I would get more power out of each stroke but I've had consistent perineum pain no matter how I tilt the saddle--and I have tilted it every which way. No relief.

The saddle is probably about an an inch to two inches higher than my handlebars. I'm not 100% sure on that, just guessing from looking at it, but it is visibly higher than my bars. So today, just out of curiosity, I lowered it about a cm or the width of a finger. (I always remembered the height it was supposed to be according to the Jim Langley site because it was the width of my index and middle finger, below my Knog Boomer. I can take pictures if it helps visual what I mean. Point is I lowered it by the width of a finger)

What a difference! Suddenly, my sit bones were positioned right on top of the wide part of the saddle instead of sliding forward towards the nose, putting pressure on my wrists to support myself and push myself back to the wide area. Maybe I did lose some pedaling efficiency but it is so much more comfortable! I think this will make a difference on those long rides especially. I might try playing with it, to see how much higher I can get the saddle and still be comfortable but I think one finger width is way more comfortable. My butt, perineum, and wrists all feel much better. I have to take a longer ride to see if my neck still hurts.

Anyways, thoughts on saddle height and comfort? Loss of pedaling efficiency?

edit: I've also read that the Brooks Team Pro is the better Brooks saddle if you ride with your saddle positioned higher than your handlebars, but I can't afford to buy another saddle, so lowering the saddle seems like a good solution to me!
