"Stay off suspect slopes."
I think that is the crux of the matter and where I intellectually disagree with that viewpoint and many on this site that talk about avy safety.
As far as I am concerned, any slope over a certain slope angle( not sure I could give exact degrees but like pornography I know it when I see it) in the BC is always suspect no matter how well I know it or have done my tests or pits or hand shears or ski cuts.

Now, the degree of suspicion must be heavily in my favor but I always retain a doubt ( no matter how small) and have an exit strategy and mitigation plan( partners in good position with good skills) on every BC slope.
As I said( and I'm not being derogatory) I truly think that many of you telemarkers who ski BC without releasable bindings( and are aware and acknowledge the increased risk they present) are in denial at the risks and try and justify it in your own minds by only skiing slopes you think are not suspect.
All slopes worth skiing in the BC are suspect and you are kidding yourselves if you rationalize that you can determine those that aren't.
I think I have science on my side on this one.

So thanks for the advice and I know it was meant well, but my son will not be skiing any slopes in the BC with me without releasable telemark bindings.

Funny. I pulled "stay off suspect slopes" and replaced it with "risk/benefit" before your last post because it didn't fit my approach to skiing for some of the same reasons you mentioned.

But that's why I tele: Risk/benefit

There is no release spring tension adjustment, and it is not DIN certified.

not quite true. You use a soft enough spring at a low enough setting and the ski will be popping off your foot all day. In the beginnig Brenda was using the softest springs at the lowest setting and the binding would actually come off at times while just climbing in tour mode. I do agree a more reliable release and lighter weight NTN would be great, and I think it would change everything, but I'm not getting any younger, and waiting for new bindings to come on the market can take years.

Little sarcasm here, but honestly, it sounds like I can pay a few hundred dollars more for a boot/binding set up that will provide me a release feature as long as I use a spring that offers no performance enhancement and is set at a tension that very possibly will pop off when least expected.

OK, sounds like a sweet deal.

There is the real benefit of no duckbill when boot packing up icy slopes...  And I LOVE bootpacking up icy slopes.

All kidding aside, I appreciate those that have jumped in on this exciting change in telemark gear, providing the R&D needed for me to some day tour the meadows above Paradise in my waning years wearing sub 4 pound solar heated boots clipped in to my din releasable Dynafit telemark bindings made of recycled car batteries and manufactured in an American factory powered by cow farts while waxing poetic to Scotsman's grankids about the days when a real telemarker had to wear big heavy plastic boots and ski on those old fat skis across the ungroomed ridge to Southback.
