Are irons too long? In particular 4 iron, 5 iron.

I’m 5’10-5’11. Single handicap. I’ve always thought the longer irons are too long (4, 5, even 6 iron). I got fitted and they recommend 1 degree upright, standard length. I’ve always thought 7 iron length was perfect, so I cut down most of my longer clubs (hybrid, 4, 5, 6 irons) about an inch to 1/3 inch, respectively. Wondering if anyone shares the same thought. Hitting a 3 or 4 iron at standard length feels like I’ll hit it fat every time. I’m choking up an inch or more on my 4 iron.

When I discovered Bryson having same length irons, it really made sense to me. Maybe not every iron but definitely the longer ones.
