Is ASSOS worth it?

First I focused on saddles. I went through about 5 of them. I finally wound up Terry Fly Tri Gel Saddle.

Then I went from Pearl Ultrasensor shorts to Campagnolo bib short. I prefer bibs to shorts.

I do some short rides (15 to 20 miles), but on weekends longer rides of 40 to 75 miles and would like to try a century ride. I do not race.

At the end of the longer rides, I can’t wait to get off the bike. My question is Is ASSOS worth it?

Correct me if I am wrong, in the Campionissimo line, there are three different models, one is T.FI UNO, then the T.FI Mille and then T.FI 13. I went to the ASSOS site. I am still not sure what the differences are in the Campionissimo line.

Can you help? Which would be best for my type of riding?

A reply with as much info with the differences between the Bibs would be appreciated

Thanks

(PS: I already use the ASSOS Crème. Great stuff)
