It depends on what course I'm playing, i.e., a longer course or a shorter course, what kind of trouble is there, are there forced carries (if so, at what yardages), what are the greens and bunkers like, etc. There's too many variables to give a general rule for your hypothetical situation. Give us more facts.
I'm not a fan of Reed but actually that's pretty funny. Spieth is inundated with fans wanting autographs... nobody wants Reed's autograph so he says to himself, "I'll just sign this here neck." So tomorrow, when he plays with DeChambeau, there will be more room on the neck for signing.
