Sometimes yes, sometimes no, it depends on how the bow feels while tillering and if there is time to shoot it in. Most often, I leave the bow strung while tillering, which gives it a continuous sweat for the entire session. When the bow is tillered most the set and/or additional weight loss is done. Most of my bows do not get there final finish until they have been strung for a couple of hours and/or shot several hundred arrows; it is the best way I have found to make the final tillering adjustments.
