Calloway Diablo Edge

I went to golf shot tried a few irons, Diablo Edge was most forgiving and best results on simulator

I bought set in 2010 (28 handicap)

Only played 3x a year

Recently got more into golf. Playing 3x a week now past two months

Are these irons outdated? I figured technology hasn’t changed that much on irons and I’m not very good (still 22 handicap). Should I look into new irons.

Thx
