Flavor will be impacted by your type of wick material more than the metal that is heading, that said, you may pick up nuances based on coil metal. Some prefer titanium. You really need a coil building mentor for your first time out of the gate. Your location is not listed, so my best advice is to go to your local vape shop and ask them to show you a build from start to finish. It is really easy, but it helps to get a good start on it. In reality it is nothing more than wrapping wire around a mandrel of sorts, then connecting the ends to your posts, adding wick material. The issues come in getting good vapor production, good juice flow and no leaks in the atomizer if it is a tank one. For drippers, it is moot as you are not dealing with a tank. Drippers are a great starting point. An hour on YouTube and you will know all there is to know about building a coil.
