Here is a White Cheeked Bulbul (Pycononotus leucogenys) ... this guy (or gal) was perched on the tip of a branch singing during a nasty dust storm ... the brown background is the dust storm but using a better beamer (on 600EX-RT) helped isolate the bird and make the background look a lot better than the horrible dust storm my eyes could see.

Nice! Do you find yourself using your better beamer a lot or just occasionally? I throw a Rogue Flash Bender on my 580EX II quite often, I just wasn't sure if the better beamer was a noticeably excellent upgrade or if was "for the birds"!
Have you used both that you may be able to comment? Seems like the BB would get me a bit more reach in some cases, I just don't know that for sure...
