I have those exact irons..O-size is oversized sweet spot..the white dot designation denotes a 3 degree upright lie angle and is for one who has a very upright swing..ie. a tall person..these are very forgiving clubs as the oversized sweet spot helps on strikes that are not in the middle of the club.. great clubs..but they are now about 10-12 yrs old...probable the grooves on the irons are worn and would need to be sharpened..if not already done so..I bought mine brand new..and just this year re-condiotioned the grooves..paying more attention to the wedges..
