I am just trying a C3 Pulse + C3 fixed Cannon, on my road to C3 fixed Plasma.
A challenge to aim with, very close-up fights required, and definitely more of a Big Snakes knotter. Yet the C3 Pulse works down even a Cobra in a satisfying short time. And no energy problems. I could imagine it is of little use in PvP, though -- or maybe it would offer WW I airfight-style combat ...
And boy, this cannon really looks like a CANNON! A shame you cannot see the muzzle from your canopy.
