CRUD duplication is fine, because if you're doing it right it's all generated from the schema at build time. It'll have columns sizes in the stored procedures, because those are the sizes of the columns as of last time you updated the schema. Rule One is "Don't touch the CRUD". The code you write touches the auto-generated base classes that wrap the auto-generated CRUD. It never need concern itself with the duplication you speak of.
