Hey everybody, just last week my braceguard broke off(only about a centimeter in length on the top has been broken off and it only goes about a millimeter down the braceguard mold) and I haven't been able to get to my maximum range lately. Although, last week I had been doing a lot of lip slurs and going into the high range a lot; usually anywhere around a high C D or E. When I started noticing I had trouble in the upper range around the notes just mentioned was2 days after my braceguard broke off. I tried again today and to no avail. Also, since I don't have any chopsaver, would just a regular Chaptick tm brand work if I had tired lips?
