I absolutely hated making strings when I used B-50, one I switched to D97, and made a decent string jig, it's been so much easier not dealing with the 9 feet of stretching from B50. But yes, I have made bows to fit strings because I hated it so much. Once I switched, I just made a bunch of various lengths so once I get to that point of tillering, one of the stings will fit. Then eventually it gets its own string.
