Trekking poles i like leki corklite but my experience is that you will fall eventually and there is a chance you will land on your pole. A carbon fiber pole will break before it bends but I have hiked with e bent pole before. I like the side lock over the twist lock because it's easier with my tent. And cork handles are a must for me. Rubber handles suck when it comes to sweat. Also you don't need shock absorbing poles.
