Custom lie for irons

So if I can't, how can I say, the irons need to be adjusted 1 degree flat because of the line transferred to the club face? I say if you are not making crooked divots and the ball goes where you aim (most of the time) then the lie adjustment is good enough. What say you?

I think… you'd be surprised how much of an angle you can guess.

Guess the angle between these lines:

3°

I would not pay much attention to divots.

You proved my point. I thought it was 5 degrees, it's 3. I was off by two degrees.

Now redraw the picture, reduce that angle by a factor of 3 three, shorten the length of the line by a factor of 5 (the length of the line above /radius of a golf ball) and tell me if you can put the ball perfectly perpendicular to the horizontal ground plane or if maybe it's off by 1 degree or maybe more.

Additionally, you have to now resolve the line on the face. Can you tell if the line is off by one degree from the score lines or 2 or even 3 using a less than 1 inch sharpie mark on the face?

So you have the inaccuracy of the placement of the ball coupled with the inaccuracy of the line to score line determination.

After all that the club fitter says, "Yep your irons are 1 degree too flat, let me adjust them for you".  ????

I think the depth of a divot measured across short side (heel to toe) can give a gross indication of a lie adjustment being needed.

Well sure enough, the sharpie marker points to 1 o'clock on my 2* flat lie club.

So I'll be getting standard spec irons next time

If you were going to bring the sharpie mark back to 12 o'clock wouldn't you need to adjust the lie of the irons by 30 degrees (the angle between 12 and 1 o'clock)?

The point of drawing the line is not to get an accurate number. It's to say "yeah, probably a bit too flat" or upright.

Agreed, I was just trying to quantify the statement I read back further that the line was touted as a more accurate indicator than a lie board or impact tape.

It probably is… but only because a lie board is not terribly accurate at all. And I don't think I made that statement.

My point in showing you the 3° line was to show everyone that you can easily see that it's not "vertical" if it's off 3°.

No, you did not make that statement, it was someone else, don't remember right now.
