Ride-fly, here's your proof of no 3 Primato. This one needs a lot of work and I don't really like showing it yet. I bought it to save it from being converted to a fixie, but it will take a while for me to find the funds to restore properly..

As for your choice, I and partial to the look of the diamante stays, so that would exclude the Professional for me. I like the sharper look of Genius chain stays but prefer the more understated presentation of the original Primato. I'd go the Primato, all other things being equal.
