If someone asked for a lens recommendation, without stating what they wanted to shoot or use the lens for, wouldn't a request for clarification make sense? B+W offers close to 200 different 77mm filters which could be mounted on the 70-200 II - that's more filters in the catalog than Canon has current lenses.
Sorry, bornshooter, but can you please explain how you think it's at all inappropriate to ask for clarification on use?
Note: after my post, the OP edited the initial post to clarify the intended use.
