The Speed +2 from mastering Myrmidon is probably better than Weight-3 because it works even if your strength offsets the weight of the weapon. It will still give you a boon, whereas weight-3 won't do anything if you aren't weighted down by weapons and equipment, and it only requires mastering a minor class you possibly aren't even going out of your way to get, as opposed to dedicating class or combat exp to a pretty bad higher tier of classes.
