Well I like the Europeans winning every time, but then I am European.
The best solution to me is to pick form. Dont go by world rankings perse rather go by recent form perhaps taking points only from the 6 months prior to the Ryder Cup ie Feb through August with the PGA Championship being the final "points" event.
Then you get consistent performers in your team, plus those who really want to play in the Ryder Cup will be evident by how many events they play in that 6 month period.
