If you can, please comment on the difference in rolling resistance and puncture resistance between the CX and Tech versions of the Vittoria Corsa Evo tubular tire. My assumption is that the Tech will have better puncture resistance, but that the CX will have better (less) rolling resistance. I am looking for any information or comments that will quantify the differences in these two variables between the two tires.
The context to this question is that I have run the CX during competitive events this year and experienced two punctures. Last year I ran Conti Sprinters over a similar number of competitive events, “race” miles, road conditions and weather. I found the CX to be faster but (alas) more puncture prone than the Contis. A switch from the CX to the Tech might help with puncture resistance (I hope), but at what cost in rolling resistance? Obviously, I want to give up as little rolling resistance as possible, and I would certainly hope the Tech is still ahead of the Contis in that respect.
A related question: the only difference between the Corsa Evo CX and the Corsa Evo Slick is the tread pattern, correct? That is, the puncture resistance is the same but the Slick would have slightly better rolling resistance due to the slick tread.

Thanks in advance for your help.
I haven’t tested the Tech or Slick versions of the Evo CX but the Vittoria Pave Evo CG 24 rolled ~ the same as the Conti Sprinter. The Pave has tread which wraps almost all the way up the sidewall and is used on the cobbles by many of the Pro’s. Comparing the tech specs both the Tech and Pave CG 24 weigh 270 grams and utilize the PRB 2.0 anti puncture layer but the tread on the Tech looks like it does not extend as far as the Pave (hard to tell from the photo on the Vittoria site). I would guess that the Tech would roll better but no experience or opinion on how it compares to the Sprinter with regard to flat resistance. I’d guess that the Crr of the Slick and CX are very similar.
