I have both the original (which is great for portrait, IMO) and the soft clear one (great for high-ceiling situations due to its inverted dome acting as a ceiling). I'm ordering another one because I will soon get another body and another flash.
I will still use the original (albeit there is a hairline crack from being crushed in my bag) for closeup (tried Lumiquest, tried Omnibounce, IMO GF LS1 is the best)
Nothing can actually replace an actual camera/flash bracket, especially Custom Bracket, but with my wrist problem, sometimes I just can't use my CB for longer than 2 hours straight and GF LS helps (and I can't imagine using 2 sets of body+lens+flash with two Custom Brackets. Not only I will continue having wrist problem, I will have back problem too, especially because 1 camera will be using 17-55 f/2.8IS and the other will use 70-200 f/2.8L IS)
