Sometimes it would be cooler for me to see a complete line when i putt or at least have a dot or :MARKER: in the balls position what cooler way to be kind to your playing partner than to have an option to mark or have the option to suggest and offer to mark another players ball. Maybe 25 to 50 cents a mark or 3 marks for 1.00 just throwing out some ideas! and have special logos or awards and accomplishments to pick your marker style. Then your marker could be apart of your bag as well!
