You can untwist (but just a little amount) to decrease the brace height,
but more healthy is to twist in order to increase the brace height.
With other words, get an 1 inch longer than normal string; with that, you
can play to get the desired brace height without the worry to do not
separate the two bundles as a result of much string untwist.
And remember, if you get a new string, after a short period it will stretch
a little bit; so, in the first period it can be useful to often check out
the distance between the deepest part of the bow handle to the string.
But all what I written, are just purely personal experiences; there are
experts here, who will tell you what is right or not.
