Congratulations, MJ12 -- this thing looks and feels professional, and seems quite smooth (if only you could afford an artist rather than cheezy computer graphics...but perhaps that's part of the charm).
Pardon me while I go cry... I was really proud of the graphics... 
One question I have -- though IMP works more or less as PEN used to (barring the 'impossible values' addition), it seems odd to me that ships can be assigned a shields value above 6...unless I missed that critical stricture somewhere. It's only noted in the 'definitions' section, and the field isn't limited to values 1-5 on the spreadsheet. I assume this is just a matter of clarification and not a fundamental change.
No, you didn't miss anything -- although there should be a mention in the construction section about the upper limit of 5.
The spreadsheet allows values greater than 5 because of the "screens" option. If you pay close attention, you'll see that if you enter a value of 6+, the box on the data card changes from "SHIELDS" to "SCREENS".
That's really my only criticism, though. I love the integral vector system in theory, though I'll have to see how it flies when I get some folks into a game or two. The new firing arcs are perhapss the most commonsense element -- matching them to the actual hex sides makes them much, much easier to remember.
People had been pushing for those for quite some time. Glad they're being accepted into the family.
