when I used to play necromunda, I differed from the other locals in terms of arming and running my juves. I would pair a juve up with one of the more experienced gangers to kinda serve as a body shield and They were also armed only with knives. they had to earn their gujns through staying alive and killing.
I would not say, it made my gang any more effective of course, but the other locals always made the jokes of how they woulda never wanted to join my gang and how they pitied the poor kids.
Anyone else ever do these sorts of chacterful things with their gangs?
