Just saw this, right after my previous reply.
Well, I did ask for perspective - can't complain if it's one that basically knocks my previous concepts into the trash bin, especially from a professional. This, of course, brings up more questions: are you saying that shorting wingspreads is such a bad strategy that it's never worth using? Or is it a matter of initial trade setup, like only setting them out at such a low delta that they should never get challenged?
(And, as a matter of keeping an eye on the ball: not my trade; I'm not defending it; I'm not even very interested in it
per se. My total interest in this thread, as stated, is to start getting a clue about more advanced defensive strategies.)
Since I don't understand the adjustment, I certainly don't insist on it.

Nor am I intent on repairing wingspreads - in fact, now that I've seen what you wrote, I'll be happy to avoid it... assuming I have some viable alternative that doesn't add up to "take a loss on all trades that aren't going according to plan." That's probably not what you're saying - but I don't know what the viable alternative is.
Been staring at this for a while, and - nope, I'm not getting most of it. I'm willing and able to work as hard as need be to figure it out, but some help in understanding it would go a long way.
"Managing risks from the outset" - are we talking hedging? Deltas outside 1SD? Setting stops at some acceptable loss ratio?
"Shorting stops" - can't parse that at all. Google doesn't have any examples of that kind of usage, either.
"Equidistant wing-strikes in SPX (not premium neutral) and DN-short futures" is the only part I think I've got, more or less - something like "build the trade in SPX so the wing strikes are the same number of strikes away from spot regardless of skew, and balance the delta with futures."
@destriero, I don't know if you can bridge the gap between your level of understanding and mine. But I sincerely appreciate your attempt to help.
