I got an Otter last eve on my subs third trip out to DS7. I'm using a straight CCCC build as I wasn't up for the expense of the one Sy part that would have allowed me two hits on the zone (I do get 2 hits on the slab back on Neolith) so RNG was kind to me. I repaired the sub before every trip back out on all parts, and sent it to DS7 as a first stop.

I want to extend a hand of appreciation for everyone in this thread that has supplied research and info on the topic. It let me figure out what I should, and could manage to build while i chased the otter, and now I can build up my FC's bank a bit.
