Anyone who uses the DaVinci cable splitters (especially the brake cable splitter) feel 100% comfortable entrusting their chamois-padded tails to these little things?

My torque wrench doesn't go low enough nor do I have as small a required allen socket to tighten the little retaining screws per spec. To get a feel for it, I took a spare piece of brake cable and practiced tightening to see how many turns it'd take before crushing it. Got that out of the way, then filed down the rear cable head (the "B" piece) just a tiny bit so a new cable would fit in the DaVinci splitter barrel. They seem to hold really well, and at full strength grab I can't get the brake lever to touch the bars, so that's a good thing. All standard Shimano housing & cables by the way.

I'm considering just getting xtra long cables and going that route instead. (Note: for now, I'm not worried about the convenience the splitters would otherwise provide if traveling, since that won't happen for awhile.)
