My Javelin came with an Arione, and it was HORRIBLE for me. I started going numb after 15 miles on that thing. The worst part was, the owner of the LBS where I bought my bike convinced me to ride it for at least 400 miles to let it break in & see if that area toughened up (it only got worse as it broke in).

The only thing good about it is that it's lightweight, flexes nicely, and it's it's a great saddle for men, so I sold mine for $90 with ~450 miles on it.
