From the first post, I thought the LHT seemed like overkill. I loved mine while I had it, but when I moved to the Troll, I never looked back. But with a set of requirements doesn't include any extended touring, and mostly around town riding and errands, I might shy away from the Troll, too. Well, I wouldn't. I love that bike, but it might not be the best tool for the job. But I do think it would do as well as the LHT on the light touring trips and might be more fun to ride around town.

But what I thought when I read your requirement was the Straggler. I see someone else has said that and that you're considering it. I haven't ridden one. But from what I understand of it's handling, it might make you happier on your group rides, while still being capable of carrying a little for daily errands and carrying enough for some overnights as well. AFAIK, there's no reason you couldn't fully load it for touring, and it'd be interesting to hear from someone who has. But since loaded touring is your least frequent type of ride, and you don't really mention any extended touring plans, I can see the Straggler being the bike that ticks all your boxes.
