Wouldn't it be safer to use aluminum trekking poles for shelter support, so if you get one caught or kick it, you're just dealing with an aluminum pole you can bend rather than a shattered carbon pole?
I've read of a carbon pole failure in a mid when two poles were lashed together and of carbon poles that broke in use. That said, I've used the Costco Cascade Mountain flick lock trekking poles for about 2500 miles hiking without a break, but the terrain was forgiving (more dirt/gravel trails and almost no talus/boulders) and I wasn't using them for shelter support. They are very high quality for the price (2/3 cost of REI) and upon putting them side by side next to the REI carbon pole Andy Skurka had recommended, found that the metal screws and cam devices for the flick locks were identical (I have photos I have to dig up).
Comparably sized carbon and aluminum poles seem to be within 1-1.5 oz weight/pair. Is there that much a benefit to 1-1.5 oz saved per pair?
Noticed also that some poles are made with aluminum top sections and carbon bottom section, like the Leki Carbon Ti (14.9 oz on Leki site) used by Justin Lichter and Shawn Forry on their winter PCT traverse, but again, you still have the carbon failure point, and the comparable all aluminum model, Thermolite XL, is listed at 16.6 oz.
I had thousands of miles on Leki Al poles including a lot of rough rocky terrain without a failure (my wife had two poles tips that got caught between rocks come off as they are supposed to, but no breakages), but they aren't flick lock. BTW, Leki claims internal locks are stronger because of the surface area engaged, and they are probably right, but I love the convenience of quick adjustment on a flick lock.
Thoughts and recommendations? I'm not looking for anti-shock, which just makes poles heavier.
