I've been using the ace connectors for adding longer leads. Should I just simply be using those yellow heat shrink crimp connectors? Seems easier, faster and cheaper. Are they reliable in the field? They were brought up before, but I want to know if they have limitations. The only thing I can think is on exposed surfaces, the black heat-shrink conceals nicely. What about servicing PAR's, should I use the heat-shrink version for those connectors, too? I've been using the regular crimp-ons with lubricant gunked on.
