Adjusting fairway loft up 2 degrees ???

[Scotland blue 36]

I'm adjusting a Epic Flash 15degree fairway from the stated ?? loft of 15 to 17 degrees which is the max allowed on the adaptor of +2.  I realize that by increasing the loft I am also closing the club face, but wondered if there where other considerations with this change.

I haven't owned a Callaway club for many years and noted that on the adaptor you can adjust loft and face angle ?? as represented by the second ring marked "N", "S", and "D".  I assume, but do not know that the n = neutral, d = draw, but s= ???  Slice ????  Any input is wanted.

Any other adjustment would you recommend when making this change ?  Thanks

"S" stands for "stated loft."  If the S is showing, then it is set on 15 degrees.  The D (draw) setting is a more upright lie to encourage a right to left ball flight.  N (neutral) is the standard lie.  I don't think Callaway's sleeve allows you to flatten the lie.  And the plus and minus signs are more or less left.
