I think that the z6 of Phase 2 clones require more aims in order to trade favorably with other common units, particularly those with red defense dice. this may come into play because the use of standby is likely to result in both units firing at each other and thus Trading. with a 3 point additional expense per unit to run the Phase I option and the current scarcity of Phase 2 clones, it is well worth considering running this option.
