Worth every penny - Black Diamond Trail Pro Shock Trekking Poles

I've used trekking poles for years now, however, unlike most backpacking gear I could never really find a reason to justify the more expensive trekking poles over the $50 ones available all over the internet. Obviously there's a huge difference with packs, and sleeping bags, tents, pads, etc. - but with poles I thought that maybe they'd be a little bit lighter, but I couldn't find any other real justification. Well, I was wrong. As with most things in life, you get what you pay for. The quality of these poles is amazing. My favorite feature is the flick locks, wow.. such an improvement over the twist locks on most poles. Unlike the twist, these don't scratch up the poles, and these stay in place. I'm 6'3'' and 225 lbs and hike 40+ miles a month and put poles through their paces. I haven't had these for long, but so far they've held up extremely well and seem to be made to last. I also really like the shock, I've had poles in the past with the "anti-shock" springs built in, but I didn't like them at all, they are more prone to break, and with me being a larger man they didn't do anything but bottom out. These however work as intended.
