When you change the gauge of a string, all else being equal, do you change the tension one way or the other? Example: you're using a certain multi in 1.30 and it has all the qualities you want (power, control, etc.) but you decide to experiment with that exact same string in a .120, to get just a little more bite. You string the .125 at 50 lbs. What tension would you use with the 1.20 to keep from losing the qualities you like about it? Is there a general rule of thumb for adjusting tension as gauge goes up or down?
