What was the ticking sound? I'd examine that bow very well. Lightly rub it with a cotton ball. If there is a splinter it will grab the cotton. So instead of breaking another record and your head again check out the bow very well. Just the fact of having the string break can be fatal to a bow, wood or fibergalss.
And why did the string break? Are the nock edges sharp or did you round them before stringing the bow?
