Don't get insulted. Different strokes for different folks. That is why there are different ways. We should try to give the OP all of the information, good and bad, for all of the methods, and let him choose his own poison.
You pointed out one drawback to the pink stuff, bad taste. I pointed out one drawback to blowing out the lines, not getting all of the water out. It has happened. People have posted about it here.
Of course, I sanitize the system after the pink stuff, then flush thoroughly. I have never had a bad taste from the pink stuff, just as you have never had remaining water in your lines freeze and cause damage.
