All of a sudden the tips are coming off my house cues. I’ve tried everything inc glues, different tips { Le Pro, Water Buffalo, Triangle’s etc) to no avail. I machine the face at 90 degrees tried pitting the face of both tips and ferrules and cutting the profile down so that the customers don’t have much of a tip to knock off. I do have a more inexperienced crowd these days with more females. Any ideas and I’d hate using slip on tips. Thx
