My trip report has a link to the videos in the first paragraph. Figured that may be more useful rather than pointing you only to the vids as I cover more things that I didn't on the vids.
I enjoyed the trip, but was too aggressive to start, which hampered me later. The MB-S wilderness is beautiful and you could do some alternate or off-trail routes that stay above treeline more in parts of the wilderness. I've found I prefer not to be walking through woods (if there are mountains to be seen).
I'm sure I'll go back again. I also wasn't trying to imply that the people were an annoyance, just that your solitude would be "interrupted" maybe 10 times a day. That should be less if you go with the flow, too. Though it depends on day of the week, too. Within a couple hours I saw at least 20 people coming up from the East Fork TH (S side of West Maroon Pass), passing by my site (never saw me that I know of) while I "worshiped" around that Sunday morning.
I do prefer going solo, but I like coming across others to chat briefly (if they wish) and share about going lighter. I talked with a trail runner at Trail Rider Pass that was doing the whole loop in a day (crazy to me though I know we have some here that do that kind of thing). He was amazed I was out for a whole week with just my "little" Golite Pinnacle. I also stayed in two "developed" campgrounds (Crater and Snowmass Lakes) for convenience and logistics sake.
