Replying to Current Tecnica Cochise walk mode issues

I could get a good deal on 19/20 Tecnica Cochise Pro 130 for 450 euros including full boot fitting. I walked around the store with them and the bootfitter said he could definitely make them work on my wide foot.

I know that the 21/22 Cochise 130 is getting the sturdy external walk mode switch, which I would love even if just for the peace of mind, but it would probably be at least 200 euros more next fall.

I read about the walk mode issues that some people had with the current Cochises. Sometimes the walk mode won't switch back to ski mode, if light snow has made it inside the mechanism. More alarmingly, some people reported that when bending the boot, it popped from ski mode to walk mode on its own. I could live with the fact that sometimes it would be hard to get it back to ski mode, but I do not want to worry about my boots switching to walk mode on their own while skiing in tough or dangerous spots. Someone somewhere mentioned that this self-switching happened only in the first production year 16/17 of the current model due to over-tightening of the spring or a screw or something like that, and it has since been fixed, leaving only the issue with snow getting in the mechanism.

Has anyone skied any of the newer than 16/17 year models and had the boot pop from ski mode to walk mode on their own?
