Why are long irons so hard to hit? What is a long iron? Given the loft creep, I'd say a long iron is a 2,3,4 or 5 iron. Mid irons are your 6, 7, and 8. Short irons are 9, PW, and GW.
Over the years, the club manufacturers made our 4 irons into 2 irons, 5 irons into 3 irons, and our 7 irons into 5 irons, at least with the loft. Change to graphite shafts and you add more length. So now I know why I hit my 8 iron about the same distance I hit a 6 iron back in 1970 when I was young and played almost every day. It's the loft and club length.
I voted "eventually" because eventually every record falls. Like the person the stat represents, father time always passes them up..
Even if Woody does get 19+ majors, some one will come along and break the new record....eventually.
