I tried an Arione but didn't particularly like it. Just purchased the new Vesta but haven't put in on a bike yet. It is similar to the Arione but has a "dip" in the center rather than a full cutout. And it definitely has a shorter nose although it is still a long saddle.

I'm struggling to find a saddle for my ultra distance rides (have completed the 200 and 300k's already this year but have a 400, 600k plus a 12 and 24 hour race still this summer). I ride a tandem. Used a Brooks some last year but was never comfortable. Tried the Arione. Have had the best luck with a Selle Italia with a cut out but never totally comfortable.

The challenge is to test alternative saddles in the next week or two without interfering with what at least partially works.
