First off, happy birthday K Dub!They were great crossing creeks. I'm always scared of having a fall on these solo excisions and these just gave me more confidence to maintain my pace over obstacles. An injury out there could be a life changing event. I hiked twenty three miles in two days and only ever saw one other person on a stretch of the PCT that I joined for about a mile. If I broke a leg up there, I'd be in a pretty bad way.
Yesterday was my 44th birthday, so I've just matured into my trekking pole phase. You don't have to be an old man to appreciate them, it just happened that way with me.
Here's another truck pic that shows the hill I climbed. I'd hoped to summit the peak, but the five miles of bushwhacking to and from the camp took the wind out of my sails (and I carried my poles under my arm most of that way). Next time, I'll camp at the trailhead and make the push.

I started using poles when I climbed Mt. Kilimanjaro in 2000 and have used them since.
But you're right that poles will bring up your pace a wee bit, especially on hills and climbs. Also burns a few extra calories using your arms!
Even walking on flats, I like using poles on account that it keeps my hands from swelling on long walks. Ever notice how they swell from just at your side hiking? Try taking your wedding ring off after a long hike with no poles....
