Best general advice about saddles---a bit higher than the ideal saddle height is considerably more uncomfortable than a bit lower than the ideal height. I have five bikes that I ride regularly and a few more that I ride occasionally, all with different saddles, almost all with the saddles that were on the bikes when I bought them, all perfectly comfortable for me. I started shrinking in height in my 60s, so I've had to drop the height of the saddles a couple of times since then, but having done so, they're back to being comfortable.
