Whats you opinions of using whips?

They are fine when used correctly. And honestly when using a whip it is more of a light tap than an overhand smack. I can whack myself pretty hard with a dressage whip or a jumping bat before it even begins to hurt me, let alone a horse who has much thicker skin than I do. Whips should be used to correct a horse who is ignoring your aids and to help encourage them forward, all of which just requires a light tap that the horse barely even feels. Now of course one should never use the whip out of anger or whack the horse across the face with it.
