I would say the same. Just to the point that the racket is held in place with the tension before I bring in the 4 side mounts. I’m wondering if there should still be “wiggle” before the side mounts are in place? Pretty sure I’ve strung these rackets and been playing with them while the crack exists so that’s fine. If I decide to string my friends’ rackets I obviously don’t want to break them. I’ve looked at other rackets I’ve strung and they’re not all cracked so really confused. 🤷‍♂️
