Need help Looking for options for a new set of irons

I have a set of Adams irons from about 4-5 years ago, they are alright, but I'm ready to move on. Looking to spend about $300 for a set, looking at Adams XTD, or maybe a set of mizunos. All options welcomed! Going to Golfsmith Friday to test.

Edit: I shoot 85-90 And I'm 20 with a swing speed of about 110mph so a stiff shaft is a possibility

Edit 2: got a set of practically new mizuno JPX 825 for 350 at Golfsmith. Added 20 yards to what I hit with my old clubs! Excited!
