I agree on getting a fitting.
I recently had my saddle height changed, because I'm using a new saddle that is a not as thick/padded as the old one. With the old one, the fitter had me at the low end of the "acceptable" range in order to try to make the saddle more comfortable. With the new one, I worked with a different fitter, and he raised it about 1/2 inch so that it was in the center of the "acceptable" range (as indicated by a device that measured the angle of my knee with my hip and ankle).
I noticed a big difference when I rode the bike yesterday, my first long ride since the adjustment. At first, I felt like I couldn't find a comfortable gear, and was spinning a lot. I lowered the saddle a bit (maybe 1/8 inch) and it felt more comfortable overall and I wasn't spinning too much anymore. But over time I started to notice that my hamstrings were sore, so I think they were working harder than before.
I also think I might be a bit faster with the higher saddle, though I'm not sure because I had a headwind for the last hour of my ride.
