“I don't agree with this statement, good training and constant practice do not protect you from freak events such as structural failure, incapacitation by bird strike or mid air collision (where you were following correct procedure and the other pilot wasn't).”
Proper training can certainly reduce your chances of mid air collisions. Structural failure due to miss handling the aircraft does happen occasionally, but again good training will impact this, wings falling off for no reason never happens as far as I can remember. Birds do not usually make the airframe to uncontrollable. If you are really wedded to the idea, and your training is safer than your first 100 h as a PPL, then find an aerobatic machine that will accept a conventional chute.
A BRS was an option on my aircraft but I sis not fit it. It can cause accidents due to reduced performance etc as well as bail you out. Excellent marketing idea, the other ½ will love it.
