AFG - I do try to differentiate between things which are my personal preferences (canisters over HOBs, silent tanks over water noise) and things which are fact. When anyone makes a broad statement without such restrictions, even when they add a smiley at the end, and it is a matter of personal choice rather than fact, I will object. There is too much bad info on the boards as is, and if my objections focus people on thinking for themselves then they are doing what they are intended to do.
