Interesting, a carbon fiber cylinder...attached to...an aluminum cylinder !
I don't know about the Katran triggers, but the Caiman (Airmaks) and Caiman X triggers are right up there on the top with the best. And yes, I now have a Taipan Veteran (that many think is the proverbial...top of the heap) to compare it to..! The Caiman trigger is actually very similar to the Taipan, just laid over on its end. Not quite as adjustable, but the design is such that it has what it may need.
I'd assume that the Katran triggers are similar.
