Can anyone tell me if the Cobra S3 Max Irons might hit like the Cobra UFI Irons?

I posted yesterday about maybe updating my clubs from my old King Cobra Oversize set I bought many years ago to something newer.

My old Cobra's are steel shaft w/ Stiff or Firm flex which I think has been hindering me a bit since I started playing again.

I was able to hit demo a few different clubs today.  They were a few "older" model clubs, but I hit some Taylor Made, Adams and Cobra.

Nothing felt good until I hit the Cobra UFI.  It was graphite YS-55+ shaft regular flex and they felt absolutely wonderful.  I hit them easily 20-40 yards further than my old Cobras and 9 out of 10 shots were straight down the middle.  Nice high shots with no sting in my hands.  I really, really dug them.

So came home and did a little research and I see the Cobra UFI's are an older set from like 2007 and thus harder to find in a nice new set.  I have been looking at the Cobra S3 Max set with Regular Graphite shafts and I'm curious if anyone could tell me if they might hit similar?

I don't know much about shafts so I'm not sure how the YS-55+ might compare to the UST-IHS that the S3 Max's have.

I'd like to assume the technology has gotten better and that the S3 Max's would hit as good but I don't have a way to find out without ordering a set.

Maybe someone here has hit both?

Thanks for any help.
