Optimisation - instead of using sets to return lists of existing LOBs & difference, iterate & act directly
Optimisation - instead of using sets to return lists of existing LOBs & difference, iterate & act directly

Using Difference doesn't help speed because it's just an iteration internally anyway, with an additional temp set. Better to just have a single set for lookup and iterate over a regular list in relation to that, and act while iterating.
