So far I can say that Titanico is more comfortable than the old saddle I had on this bike. I do have to make some fine adjustments though. The slot seems to work as expected - It lets both parts of leather move independently as you pedal. Plus, leather is suspended across the rails so you feel more like you sit in a hammock. This way Titanico adjusts to my butt and not the other way around.
This piece of leather with a giant cut in the middle is not exactly cheap. It retails for $190 (yikes!). However, there has been a sale recently and I managed to get a new one for half the price. My saddle is white, which may make it less visually compatible with many bikes (In case I want to move it to another bike in the future.), but it does match my white cross bike really well.
