Personally I wouldn't touch a windsucker with a barge pole
Wind Sucking becomes a drug addiction with horses. They are addicts. Each time they suck and gulp air they receive a hit of endorphins which is similar to a drug, hence it's addiction, they will windsuck anywhere and on anything, even on humans given half the chance.
The habit is generally caused by boredom in the stables environment and/or copying other horses that do it.
Their front teeth gradually get worn down on an angle because of the horse grabbing on to wooden rails, tree stumps, doors or whatever else they can find to achieve their addiction.
This is just my opinion though
