Gregg,
Scott Williamson determined it was more important to shield himself from the sun. And, it looks like he sometimes uses poles.

Poles or no poles? I have not decided yet whether I'm going to take trekking poles on the PCT. I've found that the umbrella trumps poles hands-down, and most of the time I don't use the poles anymore. Shielding myself from the sun is more important. The reason I might take them is to help my knees on downhill segments. However, I think my knees strengthen up after a while, and by just slowing my pace I can do fine. Plus, the PCT is gently graded, unlike trails in Crimea (Ukraine).
UPDATE 18 FEB: I've tentatively decided to leave the poles at home. If I find I need them, I can have them mailed to me.
Value of trekking poles I recently happened across an article in the Jan/Feb 2009 edition of Men's Health magazine that talked about the fitness value of trekking poles. It cited research that said that people who used trekking poles had a 6% higher heart rate (e.g. 106 bpm vs. 100 bpm, or 141 bpm vs. 133 bpm) and a 10% higher oxygen consumption rate while walking at the same speed as people who did not use them, but they did not report a higher subjective level of exertion. I have done little mini-experiments on myself, just observing my sensations when hiking at a certain pace with and without poles, and came to similar conclusions. It takes a lot more energy to do with the arms what one can easily do with the legs (i.e. propel oneself forward). This research suggests that trekking poles increase cardiovascular fatigue; however they may reduce other kinds of fatigue.
