I did the same things you all did. Iron ornamental hammer heads and then silver jav heads at 43 or 44 since I prefer to stay back on old synths as long as possible. Even though they go for 4k an ore on wutai, strangers would cough em up by the stacks for 2k an ore when I shouted to buy. Doblyn hunters can haul silver faster than I can mine it at G5, so that worked out well.
