I didn't think I'd hit the 1K mats limit as soon as I did, jettisoned a few of which I had many to make room for some new ones. Any suggestions on a top-end count per material to make sure you can fulfill upgrade needs, etc., but not have to constantly rebalance the inventory? Obviously rarity plays a big role, but do I need 50 Carbon or Iron or Nickel? Sulphur & Phosphorous (+ additives for premium blends) make SRV fuel so they get priority, but they are also easily renewed, and premium repairs are nice, too, but... how many of a mat is too many? 30? 40? 50?
