No problem, I'll be happy if my experience help for your decision, still it's good to hear others on the subject too, I'm also curios about the BRAMP system..
.

Yes, I know who Mr Marcada is, I was not familiar with his system...
Generally, I use fobs on almost all my knives just for faster drawing from the pocket, no "tactical" intent, just more convenient.
This way your thumb falls almost immediately over the opening mechanism, hole, or thumbstud...
IMO, when we're talking about some sort of self defense, the purpose of the fob is to grab it with your pinky and ring finger and draw the knife out of the pocket.
This way, your middle and index finger sort of falling over the handle and with some basic training your grip will hardly need adjustment.
Otherwise, without fob, you will have to pinch the pommel of your knife, whatever part is sticking out of your pocket, draw, and adjust your grip. Much slower in my experience.
I don't like the heavy objects at the end of the fob simply because when you hit something harder, the fob will swing and the bead or whatever you got there will hit you very hard,
avoidable issue...
As you can see, the fob on my Emerson is different than the other fobs, it is still stiff enough to stick little bit on the side and allow you to grab it without looking at it, soft enough not to hit you when stabbing hard.
I like to attach my fobs to the clips simply because I'm too lazy to disassemble them when I'm cleaning my knives. This way I can move my fob to the knife I like to carry today, to another knife - tomorrow and so on...
One more thing if you use paracord for whatever, I found that the one with the reflective threads in it are very useful if you drop your knife,
it only takes to flash your flashlight from a point close to your eyes and you'll see where the knife is. I drop my knives in attics and some other closed spaces,
helped me few times to find them.
