[TPIN] Easy lip slur exercises

[Tualatin Valley Brass]

I'm looking for any "easy" lip slur exercise book. Irons, Colin, and Smith start out easy but jump into much harder exercises too quickly for my students. I'm looking for a book that has lot's of different patterns but doesn't go above G above 3rd space C, or at least the vast majority of the exercises don't. Thanks in advance.
