I flew MS 550mm Carbon Blades on my old Raptor 30 V1, they flew really nice!, could'nt really compare with any other 30 size blade as they were the only ones i flew with that machine.
The main difference is that the MS blades are hollow and the NHP's have a foam core which makes them more solid, don't get me wrong to say the MS were hollow they were strong.
I also have a set of MS 680mm Carbon blades on my Millennium, these blades are the Competition Pro version of the blades which i don't know what the difference is but they are really stiff compared to the standard version, i think they add an extra layer of carbon cloth to the blade! All i know is i've boom striked these and they have chewed through a boom and drive shaft and not put a mark on the blades.
I like the MS 680's on my mille but i have tried a set of 710 night blades on my R90 and they are horrible compared to the SAB's.
