Hi,
between breaking a Special in, and finding the right position for the saddle if it's your first Brooks, you can be in from some tender moments. And not the chick flick kind of tender.

Ok,
start with the post clamping the middle of the saddle rails. Tilt the nose up just one notch. Some guys use more tilt, but I use just one notch, mayb a 1/16" tilt up. Yeah, sounds crazy, but it works. You can move it back from the middle, but do it in small increments.

If you have proofide, take a hair dryer and melt it. Then rub the melted Proofide on the saddle, playing the dryer over the saddle just enough to keep the stuff liquid. Do that for 30 sec to a
min at most. If you are not using fenders put some on the bottom.

There are some great leather products for breaking in horse sadles, but they void your warranty. Next, before you ride put some chamois grease on, or some really soothing skin scream.
You want enough during the break in that the tender area is thoroughly greased.

The Special IS harder to break in, but keep at it.
