Here's what I'm thinking. My experience with a 18-55mm on my previous camera often had me needing lower than 18. For that same camera I also have a telephoto that is 70-300mm which I hardly used in the upper range at all. This is why, at this point I'm leaning towards the Tokina/18-200 VR combo. After that I'll probably start getting some FX primes and see what happens after that.
Edit: The Tokina is also 2.8.
