Made it thru night 14 but doesn't really count. Had the rad-vulture issue right near 22:00 and took me a couple tries to edit the xml correctly. (game wouldn't run when I removed them so wound up replacing everything under "animalZombieVultureRadiated" with the non-radiated props) Once running again I tried the Molotovs, oopsies, 'Flame On!', heh. Got the next one off ok, then 3rd one -wasn't- the charm, no, not at all! Since I'd now made a dancing a$$ of myself (I swear I heard a zombie laughing...), and was out of water, I decided it'd be better to stop doing that. So Marksman & Bow it was. Only had 50 rifle rounds, but thank jebus I did; 1st Cop was up on bluff and his puke took off part of the porch. 2nd Cop took out some more, then 3rd Cop shows up w his Soldier buddy.
Anyway; think maybe pathing got a bit goofed due to multiple Starts. The z's cleared out almost all of the west side spikes, and they didn't need to. So while there was a spike clear path to the walls pretty early on, some just kept on blazing their own trails. In the end they only destroyed 3 poles total with another dozen or so at less than half. 3 or 4 were about a hit away from going.
They did take out a bunch of both Iron & Wood Spikes though. Of the two rings of Iron they took out ~40% of outer but almost all of the inner ring. The Iron Spikes are quite a bit tougher than the wood ones, maybe 3 or 4x?
Takeaway: I _think_ this could have worked. The extra 'skirt' I put around the supports might have confused the z's, or the restarts. Definately gave them something more to chew on instead of the primary supports. The Iron Spikes really helped a lot.
Not sure I'll try this route again though. The grind for materials really wore on me, heh.
Edit: the yellow is the one support pole they took out, the white & pink are part of the sacrificial skirt
In case anyone's interested here's the 1st horde night before & after;
