Good cutter?

I currently use a New Idea 5409 9’ 3-pt mower, pulled with JD 5525 (75 pto hp).
I like how easy this mower is to maintain but it’s getting some age on it. 1990 - cuts 70 ac of pretty heavy grass twice a year.

Has any used the new Massey version of this mower with the wire flails?

Any other ideas on a replacement cutter?
In my grass I not sure I need or want rollers?
Thanks!!
