Hi Alberto,
I use a Selle Italia nowadays. I think it is called Gel Flow or something like that. Main thing it has is the cut-out bit in the middle which works for me in a more leaning-fowards position. I also use their TT one on my TT bike.
I got the Gel Flow because I knew the brooks wouldn't work for the 24-hour TT (I remember being thoroughly sick of it by the end of the Dean and not able to lean forward on the last third of the ride without it being painful), but TT saddles wouldn't be right either as they are really designed for short distances.
But it is trial and error. The Selle Italia suits me but I am sure it would be torture for some people.
I've had the same gel flow for about 10 years on the mtb, and another one with the cut-out hole in the middle on the road bike for years too. Not bad at all, except on very long rides, when they become uncomfortable. I am going to experience with a swift for a few months to see how that goes for >10 h rides. The B17 on the tourer is good also, yet I kind of feel it rubs a bit much on my legs after a while, so got a more racey one instead...will see...
