gb 415 says: Max Fragrance:12% or 2oz./lb..... does this mean you have to add more fragrance to have a good throw? compared to lets say ecosoya cb advanced says Max Fragrance:9% or 1 1/2oz./lb.? as far as price goes the gb415 is cheaper but does it mean I would have to add more FO to it, which in the long run would make it more $..?
