Well after reading all these positive posts I also pulled the trigger on the 400mm 5.6. Now if the
weather would only warm up a bit where is the global warming when you need it.

I have been reading around for past few days, and have decided to sell my 100-400 for the 400mm f/5.6. I have not used my 100-400 much, but when I did use it, I only used it at the 400mm range.

Thanks for that info.
I have a canon 1.4x TC but as others have stated it wont auto focus with it attached, but i have also read a comment saying it will AF at f5.6 with the TC ?
Time will tell.
I think i will probably go down the same route as you suggest, shoot at 400mm then crop to suit, but for more static wildlife i will use the TC and just manual focus.
Keep us posted on how you are getting on with yours.

7D requires F5.6 to focus. With a Canon TC attached, the TC communicates it's presence to camera so camera knows it has F8 lens. Your EXIF data will show F8.
With a 3rd party TC attached, TC does not communicate with camera so camera thinks lens is F5.6. Camera will attempt to focus and EXIF will display F5.6.
You can "tape over" pin on Canon TC to prevent it communicating with camera.
1D and 5D3 bodies can focus F8.

FYI. I got my first SLR in 1985, so Autofocus is still a relatively new thing to me. I was wrong in thinking I could manually focus as good as camera.
When I got my 400 5.6 years ago I had a 20D. I also used a 5D with split focus screen. A couple of years later I got a 1DMk11N.
The 1D was much better at achieving focus than my eye / brain combination.
I was close to writing off 400 5.6 and 1.4 TC combination using manual focus. AF capability proved that combo can produce great results.

Regarding filters. Be aware of some facts. You will often see false information posted.
300 F4 has no protective front element.
300 F4 IS has a non meniscus protective front element.
400 F5.6 has no protective front element.

The hood is huge and provides excellent protection on the 400.
Use a cheap (example Canon branded!) filter and you risk poor results.
Specifically what I call "scratchy bokeh" (thanks byso)

I have never had any noticeable problems using a B+W filter.

Same here, with that rebate, it's very tempting right now. Would be perfect for hiking.
