This Cirrus bashing is getting ridiculous to say the least. If you go outside the POH, you are officially a test pilot, since you're trying something experimental. GA pilots are in general (except for Genghis and a few others) are not qualified test pilots, and if they push the envelope will get bitten - hard.
Every accident related to the Cirrus so far has been human factor or engine related - CFIT's, bad judgement, engine failure etc.
DP has a good point - a Cessna or Piper would drill a big hole in the ground just as neatly, and with less of a struggle too.
Most Cirri have the TKS icing system, but the icing could have overpowered this, or maybe it just ran out - or maybe it just wasn't switched on.
Chances are if the BRS was deployed at too high a speed it would seriously damage the fuse structure - and the shock of opening could cause the wings to fail negative if it was excessive - not that it would matter, chances are the aircraft would snap in two. All depends on how the loads are being applied. But they would really have to be going fast for that to happen.
