I think you go back to when these were historic tournaments in their own right...long before the atp.
Canadian open, italian open, monte carlo...those carry prestige....and always have.
Key biscayne and iw are awesome. I liked hamburg and paris bercy, too. Love to see a stuttgart 1000 or similar on grass.
For me, even though i am an american and i sometimes to go iw or key biscayne, the spring season here is sort of a void until the clay season and roland garros.
Now, in the modern sense, i do agree, it is about pt$, attendance, Atmosphere and how players value the title. For that, i am saying paris, monte carlo, Montreal/toronto and rome. Because i like clay, i am saying rome. But the first few days are poorly attended.
Some care about having both genders there. I do not, but i get it. Makes it more like a slam.
I liked roberto carretero, so i am saying hamburg. Haha. And it is not a 1000 anymore is it?
Ok, i will say indian wells because they get top guys to play dubs. Somehow. Hopp Schwiiiiz!
