I went with Sheldon Brown's dictum re seat height. He had posited that the appropriate seat height (in his experience and view) is where you have the seat at the highest level that precludes hip rocking. And it has worked beautifully for me. I am a little bit leary of seat height formulas, as I am not proportionally apportioned. I am 5' 10" tall, but my cycling inseam is a full 34"(86.36cm).

And I believe wholeheartedly in Sheldon's dictum, as I have experimentally tried my saddles lower and higher, but it did not work either way.
