Spring vs O-ring

For those running their malkoff in a non-malkoff and non-surefire host what is your preferred method of fitting the drop in to the head? I've had success using both the large diameter grounding spring as well as using an o-ting between the drop in and the bezel. My concern is which one is more bulletproof?

Specifically I'm running a m361 219 warm in my seraph host and want it as my one and done solo light (ie: max durability). Way I see it running the large spring it could possibly break causing a failure, but also it does allow the drop in to rattle in the head under the right impacts. On the other hand using the o-ring avoids both of those issues but then increases the compression of the b+ spring and also doesn't allow the battery shelf of the seraph to perform its function...

Probably over thinking this, huh?

Well ya but an o-ring can dry out or " Smosh" out of position. The fitting ring won't do that.

Is the fitting ring not rubber? Always figured it was!

Really? The spring could break and cause a failure? I mean I suppose it could, just as your tube could collapse under vacuum or excessive pressure. Or your battery could explode.

I'd just go with Thermal guy's suggestion.
