Islands lie amid important sea lines of communication.
Is this correct? Or should I use 'among' or choose a different grammar pattern altogether? Amid is used for uncountable nouns, whereas among is used for countable ones, but to me 'amid' sounds more appropriate in this case. Especially since amid often denotes position (which is what I need here) and among implies mingling.
I've seen a similar question with amid/among sound/sounds. There someone said: "It's probably better not to regard 'amid the sounds of the crowd' as a count usage, as inclusion of a numeral would be unnatural." So I guess amid can be used with countable nouns as well in certain cases.
Islands lie in the midst of important sea lines of communication.
or should I go with:
Islands are surrounded by important sea lines of communication.
Any advice is much appreciated.
