I'd go with just about any ski-mountaineering poles, carbon fiber with good locking adjustments and changeable tips. They have extended my Dad's life of adventure several years and counting; and any time I've got some rough ground to cover, I bring mine, which I think are Leki's -- bought them at least a decade ago for skiing, use them year round.
They really rock if you have any kind of a pack and expect some downhill.
Never mind that all our "hiking" poles are set up to become bipods with a two-ounce weight penalty for the Velcro and straps. Varmints fear us more.
