Airbag vests // talk some sense into me re: Tech-Air5 Plasma vs MAB

Hi all

So I recently got as MAB M1. In principle I should like the mechanical tether and all. But upon receiving it, in my hours of research I missed/confused two key things: it doesnt have a passive backprotector, and it doesnt have any shoulder protection that would stabilize the head (see pictures below).

It is also quite clunky (even without a back protector), and I just feel like I would prefer to wear the airbag underneath the jacket (I wear a rather comfy touring jacket, so ample room).

Now Alpinestars has released the Tech-Air5 plasma, which will be rechargeable. It is electronic, for better or worse, and self activates (I constantly forget to clip in on the MAB). Looking at the coverage though, it seems decent, but it misses the long upper and lower back extensions of the MAB.

Now in my head there are two camps fighting. On the one side I feel like "meh, I dont ride fast or dangerously anyways, and in 60'000km I havent had even so much as a near miss, so the TA5 is good enough". But on the other hand there is this aging risk-avers side of me that wants all the possible protection it can get.

Does anyone see any major risk forgoing the MAB upper back extension and getting the TA5 instead? Or is the MAB pretty spot on and the TA5 would be a considerable downgrade in terms of safety?
