I go untucked because it feels more comfortable to me. I can see the argument for heat though. When I workout with the military, sometimes I have to tuck in my shirt. I can definately tell a difference. I sweat less and feel much more comfortable with my shirt untucked. But that is while I'm running several miles. Might not be as noticable while golfing.
