i have been skiing on the old t 1's (black and yellow) for 15 years. I really liked them. I tried the BD Push and custom (uppers too wide for my skinny calves), the T 2 eco (way way too soft for me), and the new T 1 nice but a bit soft (i am sure it is a great book but the T race is better for me).
I bought the T race's this week and have skied on them for 2 days now. They fit much better than my old T 1's (even with the updated liners i bought 5 years ago). The T Race is the best telemark boot there is. If you don't believe me than check Telemark magazines review. i did and i am very happy i followed the advice.
