BOTH SNAP RELEASE??? I think so.

Yes both Auto and Non Auto Snap Release , which have different Release Points if you look at the photos. Non Auto needing a little more time to execute theoretically.

1. high hands- lower hands - does this effect the wedges?

It effects the Plane Angle of the Right Forearm Flying Wedge at Impact and therefore the Angle of Attack , impact dynamics 3 dimensionally , amount of plane shift from a TSP etc etc . Also if the hands get so low that they are below an attainable Elbow Plane you are now on a hands plane and have broken your Right Forearm Flying Wedge . If you come into impact on the same Hands Plane you have forfeited the structure of the Right Forearm Wedge........This can be done by design , for effect as a machine adjustment. V.J. Trolio for instance has a flop shot he employs from an "as low as you can go" hands plane . It takes out a lot of the Down in the Angle of Attack and makes clean contact way easier. YOu lay the face wide open so the back of the blade is laying on the ground and brush the grass with a long shallow brushing. With a flop shot a loss in structure can be a good thing , especially for really short shots where less resistance to impact deceleration is a form of an intentional loss of compression.

Sorry if Im off topic .
