I hope the Canadians get into the WG. I think it's all going to come down to where Milos is at, and I think Milos has to win both his matches. I think whoever wins between Sela and Raonic will eventually win the tie.
Shamasdin, if he ever would get selected into a tie, Israel would be the one since Israel themselves carries a pure doubles pair. But the reality is, Frank is unreliable and Milos may or may not be 100%, so they can't really afford to not carry a third singles player. And that third player should be determined by who comes back healthy, and does best during the N.A. HC season.
I don't know if Raonic can beat Sela, but I do think the Canadians can beat the Erlich/Ram. Nestor is better than both of them. Nestor/Dancevic, for example, would be a good pair. Or Nestor/Pospisil. Canada has more options and better overall talent than Israel. Plus Israel's preferred surface is hard court, so that's another positive for the Canadian team.
I think Canada is the slight favorite. Hopefully I'm proven right in September. And also I want to say again that I admire how the Canadians on this forum really support their own
