LOL, I did the same replacement you did this year. I can't tell you a lot about the tires because I'm not really that experienced or techy. They do leak a lot more than the Tufos (due to the latex, I'm told). I've got 2 races on them without problems, whatever that's worth. I ride them at 160-180 psi, but don't know if that's too much or too little pressure. Maybe someone can address that here also. Hope that's not a hijack.

i used those tubular at AZ, that 15+180 km ride its all the experience i had with them. Having said that, they didnt seem to slow me down to much :D

I believe that are Vittoria tubies rebadged, which is no knock and Vittoria makes great tubulars.

160-180psi is way too high, a sidewall cut could cause a blowout and you actually go a little slower at high pressure because the bike bounces over the bumps instead of the tire deforming. I used to make that mistake years ago and when I started running road race type pressures I was more comfortalel and faster.

I would suggest 110-130 depending on your weight. At 140lb I run 110 psi.
