For the most part I string only for myself and a couple of friends - maybe 50 string jobs or so a year. I like to string with 15L or 16g VS Tonic in the mains at about 62#and thin poly (17 or 18g) in the crosses at 52#. I play with a Dunlop AG100. So far, so good. Problem is, if I cut a full set of gut in half, the 20' of string will barely make it through the mains and I have a heck of a time getting tension on the last pull before tieing off. I do like to pull the last pull tight and use an awl to keep tension on while I tie the knot. I use a drop-weight machine. How do you all handle this? or do you just not use gut in the mains?
