Tried a friends GL Flows yesterday, and I must say "what a nice disc". Don't think it will make my bag, but only because I try not to change around very much.
Regarding the flow it seems like an easy to throw max D driver, it has decent speed while keeping a smaller rim than many other max d discs. At least it feels that way. so it would probably be easier to throw for most people. It also seemed pretty consistent in its flight.(flip up and over from hyper and fade back at the end) especially compared to the z nuke which I usually throw.
That being said I don't think it will do flat/hyzers very well unless the opto is more stable than the Gl
