FWIW, I also have that combination and have no issues with it.

.Getting back to the genesis of this post, is anyone out there actually getting their 600's that they have ordered delivered? Any insight as to why Canon is taking so long to get this lens to their customers. I have had mine ordered for some time now and am still waiting to get my hands on it...thanks for your replies!You noted that you have had yours ordered "for some time now" - how long? I have been waiting 2 and 1/2 months now and still no indication from either my dealer of Canon Canada when it is likely to arrive. Greatland, where are you and who did you order it from, not that it is the dealer's fault, but it is still his "problem". My new tripod and gimbal head should arrive in the next couple of days and I would really like to have my 600 II to test it out - obviously not yet
.
- well not really - well maybe just a bit. 
Question : I see suggestions for the GT3532... or 42. Why not the GT3531 with center column? Will the column make it unstable?
Yes - a center column is 'for emergencies only', raising it eliminates much of the stability you're using the tripod for in the first place. You should select a tripod that's tall enough without considering the center column in the height, and for a supertele, skip the center column altogether. The center column also prevents you from shooting close to the ground.
One suggestion for you and WesternGuy - I recommend getting a leveling base for use with the gimbal. With a ballhead, you can level the camera/lens with the ball, but with a gimbal you need the platform where the base of the gimbal sits to be level. If you have to do that by adjusting the tripod leg extensions, it's a real pain - the leveling base means you don't have to worry about uneven ground, just grab the stem and level it (can easily be done with the lens mounted, try fiddling with the legs like that...).
I am afraid that you might be right, but let's hope they don't find out -I'm afraid that Canon's version of Upgrade the firmware is to upgrade it so the Kenko will not work.
neuroanatomist, thank you for the explanation. Hopefully, someone in the Canon organization will wake up and see what the competition is doing and upgrade the firmware. Guess I need to put a Kenko 1.4x in my next order.

- ya, like that's going to happen - 
neuroanatomist, thank you for the explanation. Hopefully, someone in the Canon organization will wake up and see what the competition is doing and upgrade the firmware. Guess I need to put a Kenko 1.4x in my next order.I just tried my Canon 1.4x III on my 100-400 and I could not get it it AF at 100mm or at 400mm on my 1D X. Am I doing something wrong? If so, can anyone give me any suggestions as to how to make this happen?
What you're doing 'wrong' is using the Canon 1.4x. The 100-400mm is an f/4.5-5.6 lens, so putting on a 1.4x TC makes it an f/6.3-8 lens. The 1D X requires a max aperture of f/5.6 for AF to work (note that previous 1-series bodies could AF with an f/8 combo, although only with the center AF point).
Unlike the Canon TCs, the electronics Kenko 1.4x and 2x TCs somehow 'spoof' the camera into not seeing the TC for AF purposes (the aperture reported in EXIF does reflect the TC being there). Side note, the 1D X also does not see the TC for metering, so you need to apply one stop of EC with the Kenko 1.4x and 2 stops with the Kenko 2x, other bodies, e.g. 5DIII, 7D, don't seem to have the metering effect, but still AF fine).
The reason (some) people are up in arms over this is that it pretty clearly shows that the 1D X (and other bodies) can AF at f/8, but Canon is locking that function out in firmware.
Just curious - what is back focusing?
Presumably a reference to back-button AF, which I personally find very useful.
On topic, not sure if it means anything, but while B&H still lists the 600 II as 'temporarily out of stock' they've changed the status of two accessories for it, the Canon 600B case and ET-160W II, from 'back-ordered' to 'usually ships in 2-4 weeks.'. That's consistent with a previous CR post that retailers should receive a bolus of the 500/600 II in mid/late September.
