I just returned from a 4-day business trip with my Pilot. I had used it several times before for day use, but nothing strenuous. I had my camera, a water bottle, my music player, and a few odds and ends in the Pilot, which I was carrying by the shoulder strap, cross-body style. As was lifting the strap over my head to sit at a restaurant table, the bag fell to the floor. The plastic piece that holds the webbing had broken right at the hole where the swivel hook attaches, allowing the clip to pull out of the hole. I'd be curious if anyone else has had a problem with the plastic hardware on the standard strap breaking.
I'm sure the folks at Tom Bihn will rectify it, and I'll call them tomorrow. But I don't have a lot of confidence in this particular strap at this point.
