Use the 91% ISO and you should have no problems. Oh, and I have made hash the ISO way and some still came out gold. It just depends what kind of bud, trim, leaves you use. I used premature buds from my last batch to make ISO hash and it came out gold. Then used the trim and it came out gold and black. Then the leaves was all black.
