Optimising CTE for recursive queries?

In your anchor condition you have Where IsNull(MemberId,0) = IsNull(@MemberId,0) I assume this is just because when you pass NULL as a parameter doesn't work in terms of bringing back IS NULL values. This will cause a scan rather than a seek.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
