Six-pack is my personal term for Ares' standard production model: they need six different names they can put on a sculpt, preferably at least two being a second flag, to consider it for production. Oh, you should have heard me throwing fits about the upcoming French 64's... in retrospect, I DID find drawings of the two designs they settled on to share the sculpt and while there are some noticeable differences my position has evolved from "OVER MY EXTREME PROTEST" to "Approved, With Reservations," though I still have questions and reservations about the Spanish 74's (which may just be my overconservative nature--since Ares has slapped my name on their product documentation, the quality of their product becomes a direct reflection on the quality of MY work, and while they can afford to soak a few hits and bounce back I can't).
