I agree - variety is the spice of life. No need to homogenize.
However, I really like the standard UK club cards - I'm looking at examples from Burnham & Berrow and Royal North Devon, but many UK clubs follow the same format, typically having:
- Club name, logo over an old painting of the clubhouse, in landscape layout on the front
- Boxes to enter "Competition", "Data", "Player A,B,C,D"
- Colored column listing yardage and column for +/- or points
- A column called "Nett" score (what is the derivation of Nett?)
- Front 9 on top, back 9 on bottom.
- Some admonition in red printed on the fold:
"SLOW PLAY IS UNACCEPTABLE"
"DISTANCE MARKERS ARE 150YDS FROM THE CENTRE OF THE GREEN"
- Big box for Stableford points...
- Local rules on the back.
