Something to think about: Rift Lance is the small Omega version of the Phase Lance. Costs only 9 OP, fits in a small mount, half burst and fire rate, same DPS and armor penetration, has better efficiency (1.0), same range... but can get +200 more from ePD+sIPDAI that Phase Lance cannot get.
If I have enough Rift Lances for a ship, I would use them instead of Phase Lances. The stat I want most is the +200 range from ePD+sIPDAI, although the faster firing and better efficiency makes it more convenient.
