I shoot CX-100s and CX-150 Maximas exclusively. G-nock inserts are, in fact, glued into the shaft. The G-nock itself slips into the insert as a perfect fit; it is NOT glued into the insert.
Because of the insert's design, Robin Hoods are virtually eliminated. Even damaged nocks are rare.
The combo costs a LITTLE more than a simple push-in nock, but they pay for themselves many times over, in terms of arrow life.
Whatever carbon you choose, there must be a G-nock or something similar that you can use. You will love 'em.
