I'll be interested in how you get on Omar, I'm going through the same issue atm.
I've always had extremely tight gluteal & adductor muscles (remember Joy's feldenkrais workshop

). I recently popped off for a 3 day holiday at Gilfach to get me back in the saddle after my op last year. This time I was hit with blinding hip joint pain which didn't ease off, I haven't had anything like this before.
I need to look at possible alternatives for Dan who as you know is a table top! If I can't get something I may have to stop riding altogether. Looking forwards to seeing Heather's treed saddles and hoping desperately there will be one for me

. Dan is the widest size gullet in the Wow saddles, but I can't sit in them either.
Painful hips stink!
