Another track feeder wire question

[TrainHo]

Well, I kind of figured I would get both ways opinions. I put down two pieces of flex and wound up soldering a feeder wire outing the middle of the track on the bottom side. I am not sure yet but I have a feeling I will just solder wires to my joiners and call it good enough. It is a fairly small layout and I never had trouble with my N scale layout and it was down for about 3 years. I am running DCC and will only have 1-3 locos running at any time. Most likely only 2.

I appreciate the info so far and love reading how others do their work!
