hhmmm-interesting
havent served a string myelf. but he two bows i received in the pa bow trade are both served
and are not any thicker than the rest of the string.
in fact, they are so tight it appears, visually and by feel, to almost be a tad thinner.
my strings(and im just learning) seem fine without. one bows been shot lots and no fraying or anything.
the "factory" strings i have on a cupla factory bows, are only served at loops and nocking area. with lots of loose string in bewteen.
seems to work fine but i dont like it much somehow.
