I owned the Tritone (aka, "Ass Hatchet"), a couple of ISMs, a Spesh Power Arc S-Works, and nothing was the right combination of things to fit well and feel good. I put each one through road TT training and racing, which I would consider to be a really challenging test (with the goals of reasonably sustained comfort and unimpeded pedaling flow in the aero position for an extended period of time).
After unhappiness with each, I ended up testing a few loaner saddles from a shop (as Carleton recommended here), and found an out-of-production saddle which was still on the test saddle wall at the shop. Turned out that was the one I liked best, wouldn't you know it. It was the Cobb Gen 2. I searched and found a couple online floating around, put one on my TT bike, and one on my track bike. A much narrower nose than I would've guessed I would like, but I really couldn't choose a saddle based on shape and looks, putting miles in on it was the only way to truly know what I could live with.
