SS Phil, I use Vredestein Fortezza Tricomp, and have done for several years with few problems (they are 23s). I managed to melt my (carbon) front wheel rim last week by overheating it with poor braking technique down a steep descent in Austria. The wheel's a write-off, but the tyre seems fine!
On race day I take 2 or three inner tubes and 3 x CO2, but no longer bother with chain stuff as I just can't see myself breaking the chain or being able to deal with it in the heat of the moment. I'm small, though, so it could be more of a risk for the more powerful of you.
I'm now back in taper mode after the 70.3 championships yesterday - beautiful course, very hot, and a tough day, but a great experience all round. I think 2 weeks should be enough time to be fully recovered. Just enjoying a beer at the airport...
