anybody ever used this on their strings, my nocks are a little loose on my current string, its 8 strand d97, got it with my Zipper, I'm shooting gold tip 3555, I have bought a bunch of differant diameters of halo, but thought I would try the .030 so I wouldnt have to double serve, but man that stuff looks thick. Let me know what ya think of it if you have used it, or for you string building guys, what would be the perfect size/combination serving for my 8 strand d97 and GT standard nock,3555
