I've recently changed back cane from Legeres and subsequently back to adjusting my reeds. I can't remember what I used to have to do when the reed was 'fine' throughout the horn, except for a note, or two in the lower register. With Legere's I didn't have this issue, they were just 'there' for me throughout the range of the horn. When the lower register is giving me problems (stuffy, tough), I adjust area 6, per this chart**, and it opens right up; sounds and feels great. But, there are those notes that have what feels equivalent to 'speed wobbles' that I used to get on my bike as a kid.
