Backend Deals: Adjusted Gross vs. Net Profit - Best Boy's Dilemma

Hey folks,

I'm Darius, a Best Boy Electric, and I've been wrestling with something on a new indie feature. We're pretty lean, mostly shooting on a KOMODO-X with a bunch of Titan Tubes and some SkyPanel X units for key. They offered me a backend deal, which is cool, but it's a 'net profit' share. My gut tells me that's usually a trap.

I've heard stories, but never actually negotiated one of these. The producer mentioned an alternative: a much smaller 'adjusted gross' percentage, which sounds safer, but obviously less if the film blows up. I'm trying to figure out the real-world wisdom here.

When, if ever, is it actually better to take a smaller 'adjusted gross' percentage over a larger, but super vague, 'net profit' share? What are the red flags I should be looking for?
