I use `ii' and `jj' etc for all my loop counters, because it's easier to search for in any editor.
Searching for `i' requires learning the local editor's way of marking word boundaries, otherwise it'll highlight every instance of the letter `i' which is useless.
Searching for `ii' has less noise because very few words have that sequence in them, and `jj' is even rarer.
