Thanks for all your replies!

Well, technically I have not road tested either bike as I have not been able(until now) to find either one in my size. I am 4'10" so I need the smallest frames out there and most don't carry them in stock. I did not want to order one without riding the proper size first so I have been looking in multiple states..

I am visiting in Scottsdale Arizona and amazingly found both bikes so I will go out and test ride them Monday morning. Of course the Pinarello test ride will require a two hour drive to Tucson, but it's worth it. I don't want to get a bike just because it's the only one in my size.
I have never been on a road bike before (only Mtn Bikes) so trying to figure out what fits right has been difficult. Most stores keep trying to sell my a size to big and that's really irritating. I am renting a Masi this weekend which is to big for me and now I am so happy I did not listen to them, my back is killing riding this thing and braking and shifting are interesting...

I was also considering the Cannondale six13 fem1 but the top tube is 28.8
which is way to tall for me. Most bike shops have told me to stay away from getting a smaller bike with the 650 wheels as it will make me slower. Is this really such a big deal? Some smaller frames such as the Orbea only come with the 650 wheels.
Also, what about a triple, compact or standard crank?
And thanks for pointing out the Dura Ace group on the Pinarello, I had it in my head that they were both Ultegra.. Must have been thinking about the Orbea...
Any other comments would be greatly appreciated.
