Can't wait for the pics.

I have built quite a few sets of tubulars with GP4s and Record hubs.

They build up great, stayed true and were all around decent performers.

I raced on these for several years when I weighed 160 pounds.

As for the Ambrosios, I never built a set with Miche hubs. However, I did build them with DA and Record hubs and I liked them quite a bit. Pretty durable for me, but I was rail thin back in those days.

You shouldn't have to overpay for either set.

What color is your Professional btw?
