Also ... A good machine tech can re-set your machine to the thread (type and weight) you most commonly used. Each will have their standard thread they service and then set it with, so unless you tell them you want it otherwise, that will be what it will be.
Of course, you need to remember that if you then re-set the tension for a different thread, then you now do not have your machine set for your most common!
