Is this the thread to share one of my pet peeves? The usual maxing out the capacity of rear ders, even on new bikes? The Op talks about of his OCD (my term) of failures in structures but seemingly no same concerns about exceeding a design capacity. I often use automotive analogies at work. This is like buying the smallest vehicle then pulling a trailer way past the car's load limit. Sure many do this but your heirs won't see that as a reasonable excuse when your turn comes up.
