Regarding plastic connectors, neutriks work well really well. And are dead simple to connect. But they arent as cheap as the aluminium cast ones with brass connectors. And i have had plastic neutrik connectors that basicly melted when exposed to coolant and Dexron 3 oil (as i use for lubricant in some machining). Yeah its not instant and you will catch it and be able to change them.
