Talismans = everybody picking on you just to make sure you can't use it anymore. (That is, I would imagine this would/could happen.) In stock it is waaaay underpriced.
I personally consider taking organic
and crystalline (in stock) to be a bad thing - except when fighting only AIs of course
Organic Armors can repair the Crystalline Armors as well, and since the Crystallines generate shields with each non-armor-skipping hit, well..... Also, using the specialized weapons from each type (especially Shard Cannon and Crystalline Torpedo (in the early game)) while protecting your ships with this deadly mix of armors makes for the fact that your ships fight like they're a few hundred kT larger.
Side note: When facing an opponent which uses the aforementioned "dirty" tactic, simply make the Null-Space Cannon your primary weapon and place a lot of shields and no armor on your ships, and watch his ships die like flies.....
