I like the look of the Arione, but they just don't work for me. They do work for a lot of other people. This is the one area where Performance does a pretty good job. Buy a saddle, ride it for a couple weeks. If it doesn't work, return, pick a new one, and repeat. I settled on a Selle Italia SLC. It probably won't work for the guy who likes the Arione, but it's super comfortable for me.
Long story short, there is not any one good answer, there is just a good answer for you. Your job is to figure that answer out.

If you're low on bucks, try the Forte and E3 form. The E3 actually fits me well and I have one on a bike that I don't do big mileage on. It's fine for 50 miles at a time, though.
