I like heavy quilting, and my experience is that my quilts are still nice and cuddly and warm. They drape nicely, and are not at all stiff.
To me, a poofy, loose and saggy quilt is kind of sad looking. I always wonder why someone who lavished so much time and attention on excellent piecing would not want to accent that work with the final step, the part that actually makes it a "quilt" and not a "pieced work coverlet"-- excellent quilting. And STD 10 inches apart just can not float my boat.
