[QUOTE=Bem55;8895334]
I think we may use slightly different terminology - I have a windsucker - attaches to a post, arches neck and ‘inhales’. Honestly, out of all the weird horses and other things I put up with it is what bothers me the least. He is an absolute gem of a horse, lovely paces, well mannered and easy to take out places. I have another that fence walks and that annoys me waaaaay more he also throws his dinner bucket and eats off the ground, that also annoys me more than the windsucking!
Cribbing for me is chewing wood - which I agree is annoying and destructive. But honestly, if the horse is perfect in every other way I would look past it.
My deal breakers are nasty and dominant personalities. I do not tolerate aggressive or dominant horses who are constantly fighting you to be in charge, I can’t stand biting either. Rearing is also a big no.[/QUOTE]
I have always used the term cribbing instead of windsucking, although the latter is descriptive. But cribbing is not chewing wood, at least, not according to what I have heard, and not according to sources I’ve read. The Horse.com discusses cribbing (windsucking, not biting wood) in this article:

The Merck Veterinary Manual makes a distinction between cribbing and lignophagia (wood chewing):

Cribbing (Aerophagia, Windsucking)
When cribbing, the horse usually grasps an object in the stall (such as the water bucket) with its incisors, flexes its neck, and sucks air into the pharynx. Some horses will aspirate or swallow the air. In some cases, horses will suck air without grasping any object. Feeding highly palatable food (eg, grains, molasses) is associated with cribbing. Lack of exercise is also associated with cribbing; endurance horses are less likely to do it than race or dressage horses. Thoroughbreds are more prone to cribbing than other horses. The rate of cribbing is higher in confined horses; however, even if the horse is turned to pasture once the behavior is established, it will persist. It is possible that GI discomfort can lead to cribbing. One of the major complications of cribbing is damage to the incisors. Other problems include gastroduodenal ulcers and epiploic foramen entrapment. In most cases, cribbing is a benign behavior that does not affect the horse’s welfare and does not require treatment. Close to 10% of foals 20 wk of age will start cribbing when weaned and placed in stalls. Those kept on pasture will not start. It has been speculated that horses can learn cribbing by watching other horses; however, no clear evidence exists.
Cribbing can be diagnosed by finding U-shaped pieces missing from fences and horizontal surfaces in the stall, and worn incisors and enlarged neck muscles in horses that crib. In some cases, the caretaker may directly observe the behavior. Management should include more roughage, exercise, and social contact. Turning confined horses to pasture may help, and providing toys and stimulation is also advocated. Placing a strap around the horse’s neck behind the poll will apply pressure each time the horse tries to flex its neck. This essentially punishes the horse for cribbing, with the punishment associated with the behavior and not the caretaker. Alternatively, an open-end muzzle can be applied. This will allow the horse to eat and drink but prevent it from grasping objects to crib on. Some horses find a way to crib with the muzzle (eg, grasping a linear object, such as a stick), and most horses seem to tolerate the strap better than the muzzle. Keeping stalls free of horizontal surfaces and objects that the horse can grasp can help minimize cribbing. A variety of surgeries have been suggested to manage cribbing; however, the varying success rates and negative impact on animal welfare are significant disadvantages.
Wood Chewing (Lignophagia)
Like a horse that cribs, a wood-chewing horse will grasp pieces of wood with its incisors, but unlike in cribbing, it will swallow the pieces. The definitive cause of wood chewing is lack of roughage in the diet. Confinement, high-concentrate diets, and lack of exercise and stimulation increase incidence of wood chewing. Horses on pasture normally spend 8–12 hr/day grazing, while confined horses spend <3–4 hr/day feeding. Wood chewing increases in cold, wet weather. Providing more roughage, exercise, stimulation, toys, or social contact can reduce incidence of this behavior. Eliminating exposed wood and covering fence edges with wires and taste repellents can also help minimize wood chewing.
