Like your style, PJ. I can't say i've done the whole 20-mile on Magazine, but i did hook up with it from a spur trailhead about 5 miles from the summit to do part of your route. It's nothing to write home about, but it's a hike, it feels wild-ish, and definitely worthwhile. If you do more, i'd be interested to hear about your route.
In the internet age, honing in on the simplest route is very attainable, so at least for me it's interesting to hear about people going for a longer or different route.
