High TC, don't do it either too high, or close to land - by close I mean a good 100 miles by my book.
Everybody's 'high TC' is almost as varied as their mod list, some will never go above 4x, some 16, etc., I think 128 is the recommended, with 128 you'll not miss much traffic either in the air or on the water. (I reserve the right to be wrong, it could be less!)
