I have two Weber Genesis 3 burner grills that are about 10 years old each. They look identical, one is natural gas, and one is propane. They are both Craigs List acquisitions, and I got them really cheap. I don't have a natural gas line, but I would like the convenience of not having to refill the tanks. So I have not tested the NG grill yet. The propane grill works great, and I love it. My question is this, if I go through the trouble to run a gas line to my patio, will the NG grill perform as well as the propane, or better? My propane grill gets really hot and fast. So I am looking for someone that might have experience with both, or even with just NG that can give their opinion on how NG cooks. Thanks!
