See if you can take out a demo set somehow. Or at least go to an outside demo day and hit some. See if you can compare it to your steel shafted irons using Trackman in addition to how it feels and looks to you.
I’m guessing the Steelheads have lightweight steel like the xp95 so 75 gram graphite won’t be a stretch. It might feel head heavy though and “seem” heavier than your own irons.
i am trying to like them myself but I prefer the more balanced feel I get from slightly heavier steel than I do from head heavy feel I get from graphite. Also, you might not pick up any ball or clubhead speed with the lighter shaft… and some people keep the club on plane better and get more solid center strikes with steel.
