Ive been an Ast. G.C. Superintendent for over 10 years. This is just my opinion.
Usually the golf hole you will be sponsoring is for a corporate or fund raising event. From 15 + years of dealing with these tourneys i would say 90% of the players at the tourney DO NOT play golf on a regular basis. After they take their clubs out of the trunk the put their brains in for the day.
In my opinion, dont bother theyre out of the the office and or getting hammered so they probably wont notice the little sign next to the tee. If you decide to give away pro v 1 golf balls with logos, they'll be in the pond or woods before they leave the property only to be found by my high school and college employees who dont have property or money to spend.
Im sorry i have to call it like i see it, and i truely have seen it. best of luck...
