Meek broke his...but I think other people have ran them with success for a long time.
I'd probably trust the Trialtech's more as their stuff seems a bit more solid
This^^
With trials companies there's isn't a lot of money that can be thrown around unlike big mountain bike companies or road companies due to the smaller market. Due to this a lot of products are just made on the cheap to keep the factory running, which is why trials carbon bars are a little fishy in my eyes. Pretty complicated procedure, shitty factory in taiwan knocking them out.
It's a bit less worrying with alloy's as it's a basic(ish) material that is so common you can get fairly high grade for fairly low price due to its large uses.
