I was the #2 post in this thread; at that time I was using Sidi Vertigo boots.
Since then, my Sidi experience has led me to also acquire:
Sidi Vertigo Corse
Sidi Crossfire TA
Sidi Canyon Gore-tex
As you can see, I'm sold, sold, sold on Sidi. Every other boot has been relegated to the "extraneous gear" bins.
