In the US, Secession in winter, PV in summer.
Secession is busy for a winter caddie spot, nice and flat but with many varied shots due to wind. Except for the 17th, GCA knowledge is needed on most days due to wind. Can play a lot of bump and run. And I know many of the shots. A lot of gambling by members/guest and generous with drinks/snacks at turn. Seminole is also winter possibility. If I knew more about the course, no. of rounds, etc. though probably less guest play. Seems it would only be a rolling terrain, no hills, wind, great GCA. Could caddie for BJ Patton.
PV for the GCA and tips even though it looks to be more difficult, hilly for a double. Imagine you get some singles which help on wear and tear.
note: the number of bags, & amount of caddie tips cannot be discounted in todays world, possibly for another 10 years, even under theoretical GCA type questions. I offer no apologies for including caddie tips. caddie fees yes, tips NO !! number of bags NO !! Need a great GCA course with the potential of guest play considered for TIPS.
