Hi Sean, Thank you, Could you clarify your question with a little more specificity and perhaps contexts within which an answer may help you? For instance, are there any NC strategies that you had in mind specifically, or do you mean ALL of them? Are there any contexts that you are thinking of that you may wish to use NC and want to know whether a single strategy or more could be useful to use? It would help to have some form of specificity and contexts within which to answer your question so that I could answer it with the type of precision that I hope would be useful to you. ATB Look forward to hearing from you and hope I can help Robert
