lie flat or upright??

Just a general thought .... does the lie affect the shot that much?  If the lie is too flat, the toe would catch first, leave the face open and you constant miss would be to the right. (for a right handed player)  If the lie is too upright, just the opposite would occur and your miss would be to the left.  It doesn't matter what the club looks like at address (the toe up or too flat), rather what it looks like at impact. That's why you use a lie board to hit a few shots to see where you are hitting the sole.  

Am I correct in assuming this??  

I just want to make sure I made the correct decision on my new AP2 irons!  Yikes ... I would hate to send them back already to get adjusted.  It's been too cold out to even hit them and I have had them for almost a week!  I am going through withdrawal! 

Any thoughts would be greatly appreciated.

Chris, 

You are correct.  You especially want to take a look at the ball flight when analyzing your lie angles.  There are also certain tendencies that can cause certain ball flights, which is why Club Fitters will use a combination of the lie board marks and ball flight to figure out your correct/preferred lie angle.

Does this still hold true with a driver, considering that the driver doesn't impact the ground?

I found out through getting fitted for my clubs that I play 2 degrees flat. My prior set was standard and I had a nasty problem with missing left and really going left when I had a miss hit. On average I would say I was missing center by 20-30 yards left on a good hit and "im never going to find that ball on a miss hit". 

Now with my new irons and having them fitted  properly, my good hits (which are way more frequent) are dead center or right at the target and my miss hits are the 20-30 yards off center. I used to lose a sleeve of balls a round, now ive played the last two rounds with the same ball. 

I never would have guessed it made as much difference as it did but it sure does!

Preston,

Not quite.  As you noted, since the driver doesn't have any turf interaction, the lie angles can have a different impact.  To find the correct lie angle for your driver, I would refer to your 910 or 913 Surefit Performance Guide (link below).

I know that it also has to do with height of the individual golfer as well.  The taller the player, the more upright and just the opposite for the shorter player.  But my swing has changed over time.  I used to have a nice gentle draw when I was younger playing in college but now as I have gotten older, I have learned to live with it straight or a gentle fade.  I would prefer to have the draw back but was looking for a magical fix other than spending a lot of $$ on lessons ... which my ego won't let me take!  LOL

True for the most part. I am an exception to the rule. I am 6'-5" and I play 2 degrees flat. Due mostly in part to my monkey arms!
