What do you guys think is the best lubricant for brake cables. One of my brakes has been feeling sticky lately, so I want to unwrap the bar tape and apply grease between the cable and housing, but what type (i.e. relative viscosity) is best? I have everything from that very solid stuff in a tub, a very thick pourable grease in a tube, typical chain lube, to a very thin pourable lube (tri-flow). I am thinking the very thin one is best, but curious what you guys with more experience think.
