I was an early Leki user and yes, twisting was always a pain.
BD was the obvious answer and I have been very happy - went through three sets of Expeditions. Yes, I have had some sections bend, and they do not repair well if at all, but these instances were under pretty heavy abuse and BD offers repair/replacement options.
I just bought a new pair of the BD Carbon Fiber Elliptical . . . CF upper section with lower two sections elliptical Al. Spendy @ $150 but man these things are light and the elliptical shafts should stand up to some heavy torques.
