Primary key is bigint and identity, any reasons for prefering non clustered index over clustered index?

I think you definitely should have MyTableId as your the key in a clustered index without further information about how the table is actually used.

No, you definitely should have a clustered index there. That Identity field is an ideal cluster key as well.

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.
