    But I am committed to learning the sight reduction technique in Kolbe's book (described as, "a version of the "NAO Sight Reduction Tables" as used in the Nautical Almanac since 1989) so that Kolbe's LTA becomes the only book I need to carry on board. The other methods of sight reduction should be unnecessary, as I don't plan to carry any of them on board. Right?

    The NAO tables are as good as any and better than most - provided you use the Starpath Publications worksheet. (Otherwise, they are a nightmare of rules and qualifications.) That is the worksheet given in the book, but it is also available from Starpath Publications. A complete sight reduction should take about three minutes once you get slick at it.
