Club extensions?

[aceDeuceWes]

So I played golf throughout high school almost every day, probably got down to a 7 handicap during that time, and I was about 6' tall by senior year of high school. I then played a few times in college, nothing much, but grew another few inches to 6'2".

Now that I have a job and money I have started playing again regularly and I feel like my clubs, especially the 8iron to Pwedge are to short. I have been blading and topping alot of shots and feel like I have to squat to hit the ball properly. At the same time I kind of suck now, so it could just be that lost all form. Is it normal for a 6'2" person to need extensions on a stardard club length? Or should I just wait and see if my posture and swing changes.
