composite vs aluminum vs ss

[vball]

I've read about 20 threads, and I'm not sure if any thread has actually answered this question. When does composite have an advantage over alum or ss?

Many start with the question, but go down the track of analyzing one manufacturer (i.e., pirahna), not the material.

Alum - I get it, flexible, won't destroy gears if slammed, least expensive
SS - not flexible, thinner blades, longer life, will destroy gears if slammed, most expensive
Composite - ?? variable materials - some makers cost less than alum, some more - when does this application become an advantage over alum or ss?

I don't see any advantage with the composit unless low initial cost or the type you can change blades if damaged.Although a used spare aluminum could probably be changed quicker maybe even for less money.It is very likely the composte will lose a bade with a hard conntact and sometimes though rare they have a spontaenious failure.
