1) According to page 137, "Any armour that provides 7 or more APs inflicts a -30% penalty on the wearer's Concealment and Silen t Move Tests." Should this only apply to the base APs of the armour before adjusting for Craftsmanship? I would hope so since it seems odd to me that a Common Craftsmanship suit of Storm Trooper Carapace (AP 6) doesn't penalize the wearer, but the "perfectly fitted" Best Craftsmanship suit of Storm Trooper Carapace (AP 7) does inflict the penalty. Good Craftsmanship Storm Trooper Carapace (AP 6, but AP 7 against the first attack each round) creates an even more odd situation since the penalty may be inflicted based on a fluxuating AP value.
2) The Cranial Armour and Subskin Armour are Implant Systems that implant armour and thus provide APs. Unlike most Implant Systems, they lack any explanations for what benefits higher Craftsmanship versions provide. Should they be given the same Craftsmanship adjustments as worn armour?
3) The Mind Impulse Unit provides a number of benefits when they are "used in conjunction with devices capable of MIU linkage." What devices are so capable by default? Most Imperial vehicles and starship stations probably are, but is a basic hellgun or bolt pistol MIU-capable by default? If a device is not normally MIU-capable, what is the Availability for the parts to make the conversion? On a hand-held weapon, would this be a sight? As a personal note, I'm likely to limit the Good Craftsmanship MIU's BS bonus to vehicle-mounted weaponry only as i think it's a bit too strong for my game as written if it also applies to bolt pistols, hellguns, etc.
