I have already tried many saddles and who has back problems knows how difficult that is. In a specialty store here at the place I was SQLab same recommended and you mounted me different saddles that I could always try a few days. Unfortunately never had the right saddle here, but a glance at the SQLab page led me to the 603, the but the dealer did not have in stock and did not want to order. Ordered from Amazon, installed and since then I am happy with it. A perfect combination of sporty touch and gentle padding, but you should definitely pay attention to the width.
