Is it the weather first?
The type of round? (good or bad)
Just always go for it
Or is is the distance?
Personally its weather first, then the type of round I'm having, then I look at the distance last. I love the feeling of being around the green in two or even on.
Probably weather and distance for me. If it is a club I am not feeling very comfortable with, then I will probably lay up. I like to lay up when it it really windy too. I go for it any other time though.
