In combustion engine terms, having 170 cranks on legs this short is akin to having a long stroke but short connecting rods that can't take advantage of it.
It's something the roadies have actually invested a lot of research into.

Bike got quarantined till I replaced the entire drivetrain for a Shimano SLX (mostly) set
you can break even an anvil if you use a tank gun on it.
I've had RF Aeffect cranks on 4 bikes now and never had any issues. They're like $150 CAD. Got a set of Turbines now. We'll see how they go.
so there are anicdotal examples of failure to confirm your opinion anywhere you want to look. I will say though, I break a lot less wheels, cranks and bars now that they are all carbon from a reputable brand(just say no to Race face and E13).
On the other hand, when a carbon crank arm or handlebar fails it may break clean or sheer. Because this is where my body and limbs attach to the bike itself, I prefer to avoid carbon on those particular parts.
I believe there was a case reported on this very site of a broken carbon handlebar under a semi-pro rider just last year - my understanding is fully modern.
I'd love to see a personal photo gallery of one, much less multiple, AL bars that sheered.
I'm sorry you wasted so much money on bad parts
whatever you do, don't get on a modern aircraft....way too much carbon fiber to be safe! flying deathtraps!
you have literally no real world, nor engineering, nor material science grasp on what you are pontificating on.
ig·no·rant
adjective
lacking knowledge or awareness in general; uneducated or unsophisticated.
I'd look at a set of these for my Slayer.
Is it because they're just a bog standard copy of old turbines?
Extensively CNC machined, but they couldn't be bothered to use a radius tool...
Heavier, probably flexier, much more expensive than slx. Why would you bother?
What's your point?
Cross section and spindle-to-arm interface are probably more important that the alloy.
