Recently I picked up some DAL 6045 and 6x4.5 "indestructible" props from ReadyMadeRC. They are not bought and resold from Surveillzone where they are know to be available, rather they are bought directly from what RMRC claims as the same manufacturer. Trying out the 6045s I can tell they are much more flexible than nylon reinforced Gemfans or HQs, and slightly more flexible than ABS Gemfans. They do seem to be louder in the air, but this could be because they eventually end up with bent tips and nicks. The biggest question though is how durable they are, and the answer is in this quick video. I crashed this set of 6045s dozens of times, hitting trees, bushes, the ground, you name it and these props held up. The only casualty was eventually a bent blade, but no separation. The tips tend to deform slightly at the tips and eventually this causes vibrations that can be seen in the FPV camera, but not in the recording camera. Overall these are not for highly precise, high speed flying, but they are great beater props for practicing or fooling around.
Next I will try out the 6x4.5 props and compare. RMRC claims they are for slower, more floaty flying. I'll keep you guys updated whether or not that is true.
