From what you're presenting here, you're using significantly more vertical than other lispers generally. Why is this preferable to rainbow parens, ShowParenMode or parenFace (there's probably lots of other paren highlighters for emacs), to match open/closing delimiters?
I disagree that my style uses more vertical: it has one change that increases vertical and one that reduces it, and no one has done an analysis to determine the net effect.
