Yippee! If I was you I'd buy Dick a plane ticket and invite him to come fishing for a week.

I will offer a word of caution: even though you are using pre-mixed
SW you still should test it before you use it. If the
LFS is mixing it there is always the possibility that they made a mistake in mixing or accidentally filled your jugs with
RO/DI instead of
SW. Even the pre-mixed
SW in a bottle could have variation from one lot to another.
