Milos is still unproven on a grass court. It'd be stupid to do what you suggested
I disagree. Historically, Canadian players have done well on grass. Even our current players love the grass. Frank Dancevic and Daniel Nestor's best results have come on grass. Also, grass would favor Milos' game big time! It would also help Vasek's game too.
Just imagine holding our Davis Cup ties in either Calgary or BC at high altitudes on grass, we would be unstoppbale! Especially with Milos on serve!
