John S.wrote a review of Black Diamond Contour Elliptic Carbon Trekking Pole on July 2, 2012
I got mine in KTM before trekking in Nepal scratch and dent. They are great 4 season use, flintlock style stoppers, and no moving parts. I'm not sold on the spring system to absorb shock in other models for me less parts the better. I felt that these were much nicer than Leiki or even Exped's poles.
