re: home court, the drawing of lots is all done at beginning of year - see: http://www.daviscup.com/en/results/world-group.aspx
... so we are home vs. Italy but if we beat them, we'll be away at Serbia or US for semi's. If a miracle occurs, and we get to finals, we'll be home again (unless our opponent is France).
re: No. 2 singles guy for next tie, yes it is going to be interesting which 2 of Levine, Frank, Vasek get picked. But this is a good problem to have I think (been a long time since we had this problem I think).
Also note Canada is now #8 in the world! ... see: http://www.daviscup.com/en/rankings/...-rankings.aspx
