Thank U for the input !!  Well I will run them in pairs also ... Using the DRM models as I posted ...   I'll probably use the following stats **** two with -  2x 90cm MW2+ TK D3 shots, and two with - 6x 60cm AP4+/AT3+.   Now I've read a number of versions on Tau rules ... I think I'll use them as Skimmers, instead of Supportcraft ...                                                                                                                                                                                                                                                                                 **** Moray - 300 pts

Critical: The Morays weapon capacitors overload causing a massive
explosion. The Moray crashes to the ground and is destroyed.                                                                                                                                                                                                                                                                                                                                                                                                                                                

 I use the older Tau organization ... I Think the Morays will go in the Attachment blocks and the Scropionfish as a Contingent ... And I'll probably dump Knarlocs ... don't need them. And I'll add other Aliens as Auxiliary. Like CinC Felids, Reds, Martahk, GZG, Krava'k, etc. ...  It's a big Galaxy ...
