I'll agree with you that there is a lot of confusion on this thread.
First, IMR is a battery chemistry--AW is a brand.
IMR batts are Li-Mn, they are not Li-on. They are "safe chemistry" they don't have a protection circuit.
While no battery is completely safe--and yes, there have been documented cases of AW IMRs going off--they are extremely rare, and they are not as volatile as a Li-on cell when they melt down.
If the Flat Tops that were being sold as IMR--read safe chemistry--are NOT IMR cells and are NOT protected Li-On cells, that makes the chances of one going off much, much greater. When you put it in a VV device, even one with a safeguard, you are greatly increasing the chances that it will over-discharge, which could lead to a catastrophic failure.
Without a protection circuit or safe chemistry, the only thing standing between you and a battery melt down is the circuitry in the mod, and that is not anywhere close to enough protection--IMHO.
As noted before, there is a wealth of information here about batteries, and I think you would be well served to read some of it, particularly before you pick up that mod, hold it next to your face and press the button.
Here is a link with a lot of useful information for everyone. Ironically enough, it is indeed about a AW IMR cell going off. Please understand that this is a fantastically rare event, and the discharge is not as violent as an unprotected Li-On cell going off. It has lots of information that will help in the discussion.
I suggest you read it. I also suggest everyone stop using those Flat Tops unless someone can confirm that they are either IMR or have a protection circuit.

Last week I was looking at getting a Lava Tube and wondered where they found Red Flat Top AW IMRs. Turns out they didn't.
