started out hating these little buggrs but really like them now. just getting to know how to use them i guess. ive had them 3 to 4 months biggest problem with them is they are brittle , it doesn't take much to break them . i love the sound effects . im thinking of upgrading them to the metal ones. does anyone know whats the difference between the 60 degrees and the 40 degrees. i know some of you guys will say 20 degrees ha ha but which one is more suitable im not sure what to order. any feedback much appreciated
