Hackamores & Cavessons

["Linda B. Merims" <lbm@ici.net>]

Is there any reason to put a cavesson (noseband) on a horse
wearing a hackamore?

I think the purpose of a cavesson is to keep the horse's jowl
substantially closed so that they cannot open their mouth to
escape the action of the bit.  But if the horse is wearing a
hackamore, this same logic would say there's no point in
the cavesson--if anything, a horse opening its mouth would
*increase* the strength of the hackmore action.

Looking for holes in the logic, or reasons missed altogether...
