Double Harp
From Acrobalance
AKA Neckbreaker
The double harp has two bases do hand stands back to back while the flyer stands on the backs of the bases heads and stabilizes the feet of the bases. This pose is a great crowd pleaser and is fun to do. The neck is very strong and can easily support the weight of a flyer. This pose is also great in that the base is in a non-standard position. This pose is quick to get into and doesn't require much strength or balance.
Mounting
Start with both bases doing handstands so that they start upright facing each other and while in the handstand are back to back about three feet apart. Have the flyer stand between them and catch each of the bases' legs as they come up. Once the flyer has both bases' legs they can use them to step up onto the necks of the bases.
Dismounting
When the flyer steps down it is important for them to not jump down. When jumping there is an added force from the flyer that the bases won't appreciate.
