Reminds me, I put this in my permanent chargen process, should repost here-
Here is my take on the question. While LBB6-7 are usually considered inferior to LBB4-5, there are some lovely skills in there, and so while I am at it, I've put in the chance for those skills to be acquired as well, most importantly for Scouts and Merchants who would be neglected otherwise.
The intelligence requirement means a lot of these skills are rarely picked up, but gives an opportunity to the intelligent but undereducated (and another incentive to increase characteristics).
While I was at it, I went through and gave a table to all the CotI careers too. For some they are picking up LBB1 skills that they otherwise would miss. I tried to pick skills that enhanced their role- in some cases they are counter-intuitive such as the Pirate admin skill, but would be the sort of specialty that would be that much more valuable when it rarely occurs.
I also did a pass with Gambling, mostly to give unranked and rich cash table careers an opportunity to pick up that skill and get better cash results without retiring. It seemed particularly perverse to me that Scouts could not get result 7 on their cash table, or that Rogues did not have Gambling.
Speaking of which, CotI has the additional rule of getting +1 on the cash table if retired- if you retro that rule into the original 6 careers, then I'd eliminate Scout Gambling for Ship Tactics.
NOTE: Marines and Army can substitute FA Gunnery and Heavy Weapons for any Gun Combat skill result (but not mustering out equipment).
