Something we have been testing while stockpiling for HIP 9016, incidentally at 65% with 13099 of 20043—the performance of the class 3 Xeno limpet compared to the class 7 Universal limpet.
As with the class 1 Research, those four limpets from the Xeno
also each harvest Thargoids at around twice the rate compared to the Universal. If the eight from the Universal are worth 8 harvest rate, the Xeno is also worth 8 rate and a Research is worth 2 rate. For switching to the Xeno, minor compromises are losing the Collector function of the Universal, and possibly losing some Repair and Decontamination range, for what that is worth.
This changes little for the Anaconda because it has no class 3 module slot, so the Xeno limpet still displaces a class 4 corrosive cargo, although it reduces a good amount of mass and allows use of a class 7 Shield. More usefully in a way which may interest
@Phill P, those using an Imperial Cutter or a Federal Corvette have the option to replace the Universal and one Research with a Xeno and another corrosive cargo, in effect making the standard trade of 2 rate for 16 cargo. That may be useful for Alert systems where the extra cargo has a higher value!
