I'm going to say it... four-balls do not work in the current climate of the amateur game. I would go as far as describing them as a nuisance which, in my opinion, are one of the biggest factors detrimentally impacting the pace of play at many golf courses around the world.
And before I get the cliche response of... 'perhaps you should get some more friends' - this is not about social status or popularity, it's about the fact that four people playing golf together is much slower than two or three.
