Don't know what the difference between those two are but I would bet $$$ that these http://hobbyking.com/hobbycity/store/uh_viewItem.asp?idProduct=10697&Product_Name=.60_class_Carbon_Fiber_Main_Blade_600 mm and the ones you are looking at are identical. I ordered these and I will have to report that the blade chord is rather wide where it inserts into the blade grip. This prevents the blade from rotating backwards. I plan on shaving mine down a little.
I think that these http://hobbyking.com/hobbycity/store/uh_viewItem.asp?idProduct=6594&Product_Name=TIG_600mm_Carbon_Fiber_Z-Weave would be pretty cool and they look like the chord at the blade grip is not as wide either.

BTW I have a Pantera and the blade grips are rather short IMHO.

Yea those 3d blades in also availble for 430mm and i just finished up repairing my exi 500 and i notice that one blade was thicker on the grip where it mount to the heli i just sand it out a bit. They balance fairly good it was rocking on each other side very slooooooooowly. It wouldn't decide which side is heavier haha so i just put a strap on for tracking once its tracking right i'm taking it off. Have you flown you're 600mm? So one blade is wide where the insert go? Just get a rough sandpaper in fact i took some pic. LOL

I have not flown mine yet but overall it looks like the quality is real good. For $25 I wasn't expecting much.

No, the blade is not thicker, it is wider (across the chord) so that the feather shaft bolt will hit on the blade. I think a little rotary tool work will take care of that. Not sure about my pantera blade grips either, I think they might be a little short (in reach) compared to an aluminum blade grip.

If you are looking at these cause they are cheap, consider the 600mm CF Ghobees at Ghobee Aviation, they are only 50 bucks and are a ton better blade.
