i heard that it isnt possible to cut carbons twice unless u cut them beyond the end of the insert b/c it is impossible to remove the insert. anybody heard anything about this? my arrows are cut at 28 inches which is almost 1 1/2 inches past the rest so i had room to grow into them if my draw length went up. so once i stop growing will i not be able to cut them to the length i want again?

EDIT: i have terminator hunters if that makes a difference
