I'm doing some electrical work at home trying to get my shop and trailer in order so I can move in. I need to replace the wire going to them and I am at a cross road between ALUMINUM or COPPER. It will be buried inside of SCH40 conduit for the whole run and is for a 100 amp service to both places. One run is about 80 feet and the other is almost 150 feet from the pole. I've already checked the code book and I'll need either number 3 COPPER or number 2 ALUMINUM. My big dilemna is that copper is over twice as much as aluminum, but I keep hearing bad stories about aluminum failing in a year or two.

Any electricians out there have any advice to offer?
