Though Wallace may have more pages, Decker “outweighs” him by a few ounces. I wish I had Mounce at the apartment for comparison.
I look forward to exploring the grammar as I have time.
Oh, and before I forget, Decker includes a helpful “Key Things to Know” section at the end of each chapter like Black’s grammar. I always found this section at the end of Black’s grammar to be helpful for both students and teachers.
