My almost all MVP bag:
Old Shock: S-shots, shots that need to fade late and hard and sidearms. Overstable.
Volt w/ a slight dome: Longer S-shots, sweeping hyzers and sidearms. Slightly overstable.
Volt: Long straight shots, longer sweeping hyzers, power anhyzers, tailwind shots and sidearm tunnel shots. Stable.
Amp: Tunnel shots, turnovers, tailwind shots and hyzer flips. Slightly understable.
Neutron Vector (slight dome): S-shots, placement hyzers, forehand approaches, straight drives w/ fade. Slightly overstable.
Neutron Axis (slight dome): Straight shots, long hyzers and power anhyzers. Stable.
Tangent (slight dome): Straight shots, anhyzers and long approaches. Slightly understable.
Neutron Ion: Straight drives w/ fade, forehand approaches and windy upshots. Slightly Overstable.
Neutron Anode: Straight drives and approaches. Stable.
Zero Mercy: Putts!
I'm looking forward to picking up a new run Shock to fill out my driver slots. At that point I can't imagine what else I would need. I'm sure I could get more distance using a distance driver, but I know that I still have some room to grow with the Volt.
