Honestly, it depends on the people I am playing with. I play in 2 a year with my father and his work friends where I am the best golfer in the group. I tend to drive last and if no one has gotten a playable ball I will pull my 3w instead of my driver. One of the guys is a really good putter but doesn't do well under pressure. We let him go 3rd and I finish up. If he goes last he freezes and blocks the putt off to the right every time. I also play in a charity event with some fraternity brother of mine where I am by no means the best golfer. The big driver likes to go last and it is pretty rare that we don't have a ball in the fairway before he tees off. If we are having a rough time off the tee I'll use a 3w exclusively just to make sure he has the pressure off of him and can launch without regret. Basically it comes down to figuring out the strengths of each member of the group and putting them into a position to succeed. Who can handle the pressure of being the last to putt? Who can keep it in the fairway letting everyone else unleash? Who CANT be the last person to go because they crumble under pressure (put them 3rd).
