Also sounds like you need a more T-shaped saddle due to the mentioned chafing.

Which Brooks saddles did you use? And why didn't they work?

Next, have you ever had any joint pain in your hips independent of riding?

Also, you mention moving your saddle height and fore-aft position, which makes me think you aren't in the perfect place to begin with. The saddle may be causing pain because you need a good bike fitting. I've had fittings by three different fitters, and only one actually knew what he was doing.

Maybe start with measuring your bones, and schedule a fitting? Noticed this thread, lately. Looks like the most recent recommendation for your area is a fitter by the name of Michael Sylvester.
I think Muirenn might be on to something. I ride a 143 Jett, and I think it's a hair too narrow because I end up with sitbone pain at 30+, but not all the time. I deal because going to a 155 results in chafing. (Non-Brooks (and Brooks-like) saddles get less t-shaped as they get wider because of physical constraints.)
