I love starting my day with freshly squeezed optimization. And this offers an interesting optimization journey - a constant evolution of reconsidering what blocks to use, and what pits to fill.
FINALLY got it after 124 attempts... turns out my absolute first idea was correct and I missed an optimization. At least I can confirm the ungodly number of 2- and 4-off paths all do a suitable job obfuscating the correct option!
