The tour model is the same as the standard model with the exception of the removable handle with a stainless steel spring. The pros and their trainers like the tour model because it allows them to set the proper wrist angle at the top of the back swing. This is much more natural and serves to reduce pressure in the small muscles of your hands and arms which in turn engages the big muscles of the shoulders, back, and abs. The use of these big muscles is essential to a powerful and repeatable centrifugal golf swing.
