Do you find yourself using a common fill (run,etc)? Do you use it as a crutch, do you actually like the way it sounds or is it just a habit. I listened to recording of my self at practice and never realized how much I use the ole octave, seventh, fifth, fourth roll down. Not really sure how I feel about it. They were mainly all improv sessions, so I'm hoping it was just a subconscious thing.
