I very much appreciate the variety of perspectives on this site, as well as the wealth and diversity of experience! I generally take a very unscientific approach to all this, so I try to glean what I can when I can. That's a very good point about the shock absorber too. I was sort of thinking of tossing this with piece of rebar and 65lb braid, so I'd better take some of those stress limits pretty seriously...
The first bunch will all have the lip in the original position, as they are already cut, and then I'll adjust as needed.
