There should be no aspect of training that imprints tension. It's ok once in a while to have someone stupidly resist but its just as a check that you know what you think you know. Daily training is about programing your mind and body to think that relaxing will make it safe rather than tensing. If half the time you are tense, your poor body simply gets confused about what it should do.
A great post that really needs to be read and thought through more than once. This is the essence of what I believe I am trying to say.. where I believe it is vital (to re-use the word from the poll) to spend the bulk of my time.
