I have been playing DCI oversized Irons since College and love them.  Recently my family wanted to give me new clubs for my 50th birthday.  I went to PGA Superstore and got fitted.  Originally I got the T150 Irons but my dispersion is far worse with them than my old irons.  Misses feel very dead as well.  They are letting me try a t200 iron, but I feel the distance varies on shots, dispersion is okay, still get a dead feel on misses but not as bad, and my ball flight is lower than DCI and T150.  I have been playing with the new clubs for 2 months, hit thousands of balls.  Nothing feels as good as the DCI.  I do lose a club distance with DCI but gain control and feel.  Getting fairly frustrated.  I am a 5 handicap.  I feel this shouldn't be that hard to switch clubs.  Any recommendations?
