I'm Chris from South Carolina here! Finally bought my first beginner set after years of flirting with game! Can't wait to pick them up this week! I am totally excited to learn from you fine men and women about this great game!
Based on my driver distances I am pretty similar to the OP. For me any course that totals greater than about 5,800 yards is just too long for me.
I read somewhere that if you’re not competing but just playing for fun you might want to try playing variations like a “red, white and blue” round. Meaning - play the par 5s from red, par 4s from white and par 3s from blue.
Depending on the course that might make those longer courses more accessible.
