If AF speed is critical, a 100-400mm or 400mm f/5.6 will AF faster than a 70-200mm f/2.8 with a 2x TC. The 2x is useable, just not ultra fast. A 1.4x TC will be pretty darn fast.

good to know, I think the reach on the 100-400 is pretty good, I just dream of options
but i won't really be able to explore those without the AF (yes i could manual focus, but fear of the missed opportunities due to clumsyness)
And this is why we go big megapixels, we can digitally zoom by cropping
thanks for the info guys. You've confirmed my suspisions.
