One thing I have been wanting to add about the flight difference between the Shock and Volt.
If you watch the Disc Nation video, there is a clip of back to back comparisons of the Shock and Volt on shots that move left to right(for RHBH). It is the part where the Shock goes into the Soccer net. The volt needs a lot more air to get a shot that will flip up to the right and then fade back left. The shock however can hold long low flat flips, where it tracks right and then fades left with only 10-15ft of air. The Shock is overall much better at holding low lines that will not bounce around in the air
