Ive had a couple wedges with the DG Spinner and I personally dont feel like it spins any more than any other wedge shaft Ive ever had.

Take a look for high launch and hi spin
The DG Spinner has separate shafts for PWs and GWs, than for SWs and LWs. This goes for both the original and the more recent one with a flex point at mid-shaft.
