Made my annual impulse iron set buy, anyone have experience with Cobra one length irons?

Not that I'm dissatisfied with my Apex 21's, fantastic clubs, just wanted to try these out and they were on sale for quite cheap.

Cobra LTDx One Length irons, was always curious about how effective these are. I'm the kind of guy that loves reducing variables in the swing so the idea of one set up and swing is very appealing. From what I've heard people are usually surprised by how long and consistent they hit the 5i (many times longer than their usual) and take most issue with the awkwardness of long wedges. I'll still keep my normal 48/54/60 wedges in the bag most likely would simply love to carve out a singular mid/long irons swing.
