I found there were some very small hair size cracks at the corner of my LM prestige's thoat. It is a fairly new stick, only about 1 month. Since Head uses so called twin tube for LM prestige, I am wondering whether the hair size crack is structural damage. I did not feel different when I hit. The cracks seem not deep. I think the inner graphite part might be good, the crack is only on the Intellifibers part. Anyone met this before? Thanks.
