can we talk plug gaps?

So should i just leave them alone gapped at .050? or should i back them back down to .045? My distributer is brand new and i have a good cap with copper inserts instead of brass (better conductor) and I have a good rotor. I am in need of some better plug wires i'm sure, i currently have borg warner selects 7mm wires that test out around 450 to 500 ohms of resistance per foot. I'm thinking about getting some taylor wires or some crane fire wire in a 8mm or 8.5mm.
I know the plugs wear over time and .055 might be too much of a gap, so i am leaning towords dropping them back down to .045. But my plugs are indexed and are brand new. But still i wanna be safe from miss fires. so what would you guys do? call it good at .050 or pull em back out and go back to .045?
