My only question would be whether the 200-500 is too long or too big a diameter for the large OpTech. It is certainly worth picking up a 2 pack for the price and testing - worst case use that for your shorter lenses. If it doesn't fit the 200-500, then I'd spend the $$ to get the fancier setup. If not, I'd go OpTech or similar as they are much smaller and lighter. I knew that even if the OpTech fit the 200-400, it would be very difficult to get on and off in a large part because of the diameter of the lens. With shooting sports in pretty much any type of weather, I knew I had to spend the money so I actually got the rain cover so that it arrived before the 200-400 arrived! It wasn't going out without available protection and I knew I'd want to get it out ASAP!
I bought some optech rain sleeves and they fit the 200-500 just barely. The only problem would be the collar mount is covered but that's perfectly fine.
