[support] Deciding which view based on argument?

[Luke]

I am no views expert.

I am making a view which shows listings of nodes (products) in a specific 
way, if they are in a certain category.

I.E.

If the term is one of: 7, 10, 20-30, etc., the view should show the 
listing one way.
If it is anything else, it should show them another way (the default 
UC_Product view, actually).

How can I do this?

Do I use two views, and some how determine which one is accessed by TID?

Or can I do it with a single view, and some how choose the display by 
argument or range of arguments?

Thanks

Luke
