There's no wrong answer. Some people shoot a very heavy arrow, and that has it's benefits (quiet, great kinetic energy...but slower). I don't like an excessively heavy or excessively light arrow. Most bow companies recommend a MINIMUM of 5 grains per pound of bow weight. This would put you between 325 and 350 total weight for a 65 or 70 pound bow. I think around 385 would be a good reasonable weight. You'll shoot a little flatter and therefore your pin gap will be a little more forgiving towards yardage estimation.
