I have read that a larger brace height is more forgiving of less than perfect form. What is considered a generous brace height?

I would say anything around that 7.5" range or higher is pretty "generous". Though you'll find some of the bows that have a lower brace height (7.5" or lower) are often very forgiving still. Good luck!

7 or higher will do just fine

I think 7" or more is a general rule of thumb.

I think draw length can affect the BH which is forgiving to a shooter. I am a 28" draw and have shot the BowTech Airborne 82nd all summer with it's 6.125" BH and I have never shot a bow better.

The new bows out also have the string stops, which seem to get rid of the traditional low brace height problems.
And I have a short draw, so tht helps a bit.
