A previous poster noted the stall speed of the Cirrus as 70. That's ten it's too high in fact....its 60 in fact....and of course, that's at max gross weight.

I was the one who posted 70 MPH. For the past couple years I've been reading this forum, it seems that MPH is generally used more than Knots. I use MPH in my STOL 182 and I did in my Kitfox. At the lower speeds it provides a bit more precision.
Per a generic 2011 SR22 (Generation 3) POH, the full flap stall speed with zero degrees bank angle is 62 KIAS, so I converted to MPH in my head and rounded down. (I'm pretty sure my Generation 2 lists 59 knots indicated.) I also figure that in a real life forced off-field landing, I would be so careful about not stalling it, that I would likely impact a couple MPH above the POH stall speed, so for the purposes of that rather lengthy post I wrote, I felt that 70 MPH was a round, conservative number that made the point that these are not STOL planes and there will be a large amount of forward kinetic energy to dissipate.
BTW, I wanted to thank you Mike, for carefully dispelling the myth about the Cirrus needing the chute because it didn't recover from spins. That was a very cogent presentation of the facts and data.
I've been away from the forum for a few days. In response to Cary, well yes, I guess I was a bit sensitive to how you combined references to Cirrus drivers with phrases like pilots of "dubious" ability "taking chances"; and contrasting our actions with those of "more skillful pilots". One of the things I love about this forum is that--other than good-natured ribbing-- Cessna drivers (for example) don't generalize about Cub drivers when one of them makes a mistake and pays a hefty price.
As far as your picking a ten year old case of generally accepted bad decision-making and implying that that was what I meant by changing my mission profile and ADM as a result of the BRS, well, if I wasn't offended before, a guy could get offended by that!

BTW, if anyone is interested, that Norden, CA crash prompted a detailed analysis, with audio/video re-enactment that is quite interesting (Sorry, I don't have the link at hand and I'm rushing a bit). It led to a review of the NWS icing reporting as there was no icing airmet or sigmet provided in the briefing.
It was still a very bad decision, but no one in the know thinks that guy launched into the teeth of a winter storm over the Sierra Nevada Mountains at night in a piston single because he had BRS. In fact, the evidence suggests that it was automatically deployed as a result of stress on the cable as a result of the airframe coming apart when it was a 300+ knot, iced-up, nose-down lawn dart.
As subsequent posters pointed out, even if the presence of a BRS did occassionally contribute to a bad decision, the saves still far outnumber the induced crashes. That's similar to the conclusion of all the highway data. Even though we drive faster with seatbelts, airbags, and ABS, the lives saved far outnumber those taken.
In another thread, helmets are being discussed. Before reading this forum and seeing them at the Anchorage show, I never even considered wearing a helmet in flight. Then again, I skied for thirty years without a helmet but now I always wear one (In fact, it's mandatory when I'm on the clock as an instructor at Heavenly!) So while I haven't rushed out and bought one, it's got me thinking about what sorts of flying it might make sense for.
edited to add this reply to Kelly's post:
In reply to Kelly, about the long over-water flights, yes, the BRS has been used successfully for water ditchings and, along with the rest of the excellent equipment package in the Cirrus, contributed to my decision to do those flights. I don't recall the stats off the top of my head for ditching fixed gear planes in the open ocean, but the incidents of fatalities and serious injuries from the rapid deceleration from landing speed, and flipping, are significant (maybe around the 25% range?). The videos I watched before getting in the pool during egress training stuck with me!
