honestly, never had it slip with the diff greese... rubber cement is a badddddd thing to use, honestly, don't use it!
One trick to help (and this is something I pointed out to the friend i was showing how to build a diff), is too sand
both sides of the diff ring. a) this gets it flat both sides, and b) it provides a key for the ring to grip against the outdrive. I'll go 600grit on the outdrive side, but 1200grit+ on the ball side.
As for the extra balls, I can't see them making a huge difference in a lighterweight TC. Yes the loadings going through the diff can be quite high, but not as much as when a 4wd buggy lands of a jump on full beans
IMO, I wouldn't bother, but maybe something to try out
