Darryl, the 14-1-14 is a nice pattern with good visual appeal when using stainless button heads. If using rivets I would run the 15-1-15 but these days most people like the stainless button head bolt look and ease of fitment/removal and so the 14-1-14 works well.
We have scoops with 14-1-14 pattern imprinted or plain. So very quick and easy to fit with that pattern. We will keep doing numerous versions of our scoop.
Where did you read the 15-1-15 & 12-1-12 are the most popular. That sounds like something I might have written...
