I was stalking the Arione Donna for a while before it seemed like anyone was actually selling it, and this thread got me onto it again. I was surprised to find it at a local shop's bike expo last weekend at 20% off, and they have a 30-day return policy.

Wasn't crazy about the flowery look in pictures (even though I wear blue flowered Sidi shoes) but like it better seeing it in person. It's more subtle than I expected and it's sleek and light but still wide enough for me. I've been pretty happy with the Fizik Vesta but was hoping the Donna's flatness would give me a better feel that I'm really sitting on my sit bones. The Vesta swoops up in back and lately leaves me feeling a little too tilted. Although they seem about equally cushioned (not too much) and have similar channels, after 18 miles yesterday and 25 today, my initial impression is the Donna feels harder/stiffer. Not sure I've found saddle nirvana yet but think I like it better than the Vesta.
