Of course, NT is always the topic number one, when talking about the python. For my part, this problem is solved by the "hanging pendulum" effect. Last year I rode upto 70 km/h downhill without feeling unsafe. In the flat I reached 40 km/h. Braking at high speeds caused no instability. In the very beginning the bike started to wobble at higher speeds, but this was because there was too much play in the rear suspension. I understand that everyone has to make his own practical experience with this. The NT item can not be discussed on a theoretical base alone. Driving dynamics is a complicated mixture of multiple forces and even the experienced frame developer cannot predict wether a given design is well rideable or not.
