70-200 F4 Heavy Breather?

Shotcents has a bizarre personal vendetta against f/4 zooms so its no surprise that he has come out with unsourced second hand anecdotal evidence as soon as he could against this lens. The thread will proceed with him telling you that you would be an idiot to buy this lens as it no better than the 70-300 while also saying that you should get an f/2.8 zoom instead that is "only" $1000 more and weights "only" 24 ounces more.

You will find evidence that refutes his claim but he will insist that he had three different copies and they were all junk and no better than his 70-300 which is so much sharper and so much lighter, why would you carry that extra weight? Except he will also tell you he is so worried about IQ he carries his 70-200 f/2.8 everywhere he goes.

After about twenty posts you will find his wonderful setup weighs twice as much and costs twice as much while he is trying to argue his brilliance on saving weight and not getting ripped off by Nikon.
