The value of Goldstrike Arch might below 1fg, but if you have a very good one I am happy to offer high price for it
700 fg 4 Perfect Goldstrike Arch (250ED, 200DTM, 200DTU, 150 AR)
100 fg 4 very good Goldstrike Arch (250ED, DTM+DTU+AR > 540, or two out of (DTM, DTU, AR) are perfect)
I will keep it for now, if i can not find very good one will gradually reduce the constrain (the sum of DTM+DTU+AR) )
