Yeah that wire looks better than what I could get at my local.

Deans claim their connecter has less resistance than the equivalent length of 12ga wire. What kind of 12ga wire is doesn't specify (at least were I read it). I'd stick with bullets, deans just look so little an poxy once you have large wires.

Castle have high strand pure copper silicone 10ga wire, and 6.5mm bullet connecters.

Not sure about your wires, but tinned normally means coated in solder, it looks like yours are not (maybe they coat individual strands I don't know). Cheaper wire has tin strands which are much higher resistance than copper.

All that said and done I've used a combination of castle 14ga and deans wet noodle all with 5.5mm bullets, and have never noticed any of the wiring or connectors warm up under as much stress as I can give it. (running 4s buggy or 6s revo geared for ~40mph).
