There’s a lot of tourism. The CT has to be one of the most highly documented trails out there. There’s no permits required and there’s only a short season when the passes are clear. There’s sections you’re warned not to camp in because of all the existing cat holes.
Yes, any time I venture near the CT on a trip, I’m reminded of why I want to avoid it. Some of the terrain is lovely, but it’s effectively an ant trail for people who like to be around a lot of other people while hiking/camping, which does not describe me. But hey, if it keeps the out-of-state visitors concentrated to one highly publicized corridor, that’s better for me, so I really shouldn’t complain. :-)
Apparently the annual event is going strong. Yesterday, as I was returning from the South San Juans on 285, I saw a couple of people (apparently through-hikers) walking on the shoulder of the highway. I never noticed people there before, but perhaps it has become a re-supply point. I saw many others on Kenosha Pass, of course.
Anyway, that’s obviously off-topic. I’m not sure why some people are talking about “marginal” or no rain gear. Every option the OP mentioned is a solid choice that would be sufficient to keep him safe, assuming he has insulation/hat/gloves, etc. Some are lighter and more compact and others will keep him more comfortable if he has to hike for days in unrelenting rain. Just the usual trade-off that involves personal preference.
