Chain wraps on a hollow tree will seldom be of any real usefulness. If the tree is thin and hollow, a chain wrap may only force the wood to collapse inward, rather than outward. Applying load-binders to the chain are likely to force the collapse prematurely.
Barber-chair is not very likely on a hollow tree, as there is almost no wood left to split. The tree usually falls over before it can generate enough force to cause a longitudinal split.
Hollow trees are very tricky because they collapse on themselves and fall unpredictably. The best approach is to remove supporting wood on the side you wish it to fall towards, and you should probably be ready to pull it over with a high rope. Wedging a hollow tree over is also rather unpredictable.
Whenever possible, try to fell it in the direction that leaves the strongest hinge wood possible to hold the tree up while you are still sending it down. This allows some control and safety while you are getting away from the tree.
