It’s sounds more like your are trying to make your new purchase with no regrets. Personally I have tested both the 600mm ll and 800mm. I believe both have their strong point and weaknesses . The 600mm with 1.4x tv still could not produce the sharpness of the 800mm. From the start of your article, you sounds very eager to say “My new 600mm is the best in the world!!
Anyway with a weight of 500g difference and completely different specification between the 2, you claim the winner is the 600mm ….??

Well, i will try if i can get 600II from someone to test it and make my own AF Guide, and if it work great then i can share, but honestly speaking, you don’t need one, 1DX is a remarkable phenomenal camera, more than 1 year i use it for sports [soccer] and it never let me down, AF is way better, sharpness is noticeable with same lens i use on 1D III, so you are right that it is a Lamborghini to the 1D III’s soap box derby car.

I didn’t read the whole replies here or maybe i forgot if i read it, but can you tell me again how much lose of AF speed and IQ when you use that Canon 2X III TC? i don’t think it will help much for my version 1 lenses, but sure it will shine more with version II lenses [ i have only 70-200 version II].

Hi Tareq, Please do not take this personally, but as far as your question about AF speed and IQ, I suggest that you make your own 1D X AF guide and then answer your own question. artie

ps: folks who have used my 1D X rave about it and nobody but me has info on my Custom case for photographing birds in flight. Maybe when you are done writing your 1D X guide you can send me a free copy.
