I think that the Astra by FXC has been under-rated. FXC are more involved with the military side and for this reason 'saves' by Astra are not normaly recorded in the public domain.
There are a few stories about FXC 1200 mis-fires that seem to have been confused with Astra mis-fires.
Our club now use Astra's on their rigs, to-date none have had to be used, but I have all the confidence in this equipment after having talked to FXC, read the spec and talked to riggers.
Just because it is not 'main stream' should not cloud judgment.
My advise is, find all the facts, talk to people in the 'know' and only then , make your choice.
Mine was Astra :-)
