Full disclosure, the Aliante suits me better because I rotate my hips forward when riding even though I am flexible like the chameleon archetype. Focus on hip rotation more than spine flexibility when choosing Fiziks saddles helped me choose the right saddle.
The Fizik weight average speed saddle width decision guide also worked for me resulting in a wide saddle width even with 120 cm sit bones.
It is a lovely saddle that looks as nice as it is high tech... Dense padding and enough flex but not too much. Oh and light too.
This makes my fourth Fizik saddle over the years. I was replacing a older version of the Antrares saddle, and remember how long the previous saddle took to break in. This one was dialed in right out of the box. Absolutely the most comfortable saddle I have ridden. I highly recommend it.
