I have never worked with index lines so this was a nice intro to the variant! Really nice logic throughout!

I like the new ruleset. Though the way it works in pairs I think may be a weakness that could prevent it from being flexible enough to be widely used. Maybe there's a way it could be modified to have cycles that are longer than 2?
