I recently decided that the mare and I are done with competitive dressage, and we'll noodle around until it's time for her to be retired and/or I buy another horse. (And, sadly, until my father passes on, because his needs mean that I am too short of money and time for "serious" showing.) She is not 100% sound, nor am I, and I need for my horse activities to be FUN and my horse to be HAPPY above all right now.
So... I've run across the "ditch the noseband" idea in various circles (e.g. "French School" thread here, the huge flame-fest on FHOTD when Mugwump was running it) ... and knowing that the mare is fussy, I pulled the noseband off her bridle last week, and she's been *awesome*. If we're not showing, it doesn't matter whether she wears a noseband or not. She's softer (and has a super-soft mouth to start with), she's not trying to get her tongue over the bit or opening her mouth or running away with me, all things I feared would happen. In fact, she accepts the bit better now!
