Copper vs felpro vs ? head gasket

Why do you think you need any gasket other that a standard replacement gasket. For normal or moderate "hop up" I like the OEM "shim" gasket, but these are getting hard to find. A fel pro is an OK gasket but any aftermarket replacement gasket will hurt you compression ratio, as the are thicker the the oem gasket. In my opinion a copper gasket has no place on a stock to mild build. They can be a pain to seal water and oil, and idealy use "O-Rings" around the bores.
