Massey Rotary Rake

Wondering if anyone has ran a new Massey Rotary Rake? I saw where the have the ability for the rotors to flex to follow the ground better. We have some rough leased land, and very hilly terraced land. in general, Will these big Rotary rakes get the hay up on bumpy and rolling terrain? And will they hold up? We currently run a 10 wheel Kuhn speed rake, but want to keep the dust and debris out of our hay.
