There are a couple of threads here on measuring your "sit bones". It is a bit of contortion, depending upon your..uh...errrr...natural padding level, but worth it. When I did that, I discovered that my 6' frame did indeed have a wide sit bone distance. So, then I started looking for saddles that were a little wider than the spacing of my sit bones. Argggg.....the struggle began.

The saddle I've gone with is the Selle SMP Strike "Lady". It is wide enough to support my sit bones and has a generous cutout to relieve pressure. It is, however, a bit softer than I'd like, but I haven't found much alternative. The primary complaint about the saddle is the width of the nose--it is wide, but, for me, it works. It is best I've found.

One of the wise ones on these board said that they know the saddle is wide enough when the sit bones hurt after a long ride. For me, riding the Butterfly, my sit bones never got sore. What would happen though was after riding for a while, when I stood up, I'd have terrible pain in the coccyx area--it was as if I'd stretched out the muscles and they were slowly moving back into to place. Hard to explain, but, in retrospect, I believe that is the indication that the saddle was too narrow for me. I wasn't sitting on the sit bones--I was sitting on soft tissue.

Anyway...if you haven't tried to figure out your sit bone width, you might want to search for the older threads. From what I've read on the board, height isn't necessarily a good indicator--it all depends upon your bone structure.
