Bullshit. Really. This post contains some serious bullshit.
Alright, well explain it to me and I will take it down. I try to get my information right, but I'm not always right. I'd like to hear what you have to say. I think I've got a handle on it, but if I truly don't then let the facts reflect that and I will take this discussion as a valuable learning experience.
You seem really frustrated with what I said. I'm not offended, but I am curious. You've got me thinking, "My god, what did I miss that's got this guy thinking I'm such an idiot?"
I feel like an idiot, but I don't know why I'm an idiot because you haven't explained it to me and I sure as hell can't figure it out.
Now that I have some time, I just want to elaborate on what I was saying before. I'm not making this shit up and I have reasons for thinking what I do about materials. Hear me out and correct me where I'm wrong. I'm not trying to argue with you here - I just want to understand this better, so I'm trying to make my points as clear as possible.
I am aware that copper is orders of magnitude more conductive than SS. All I was trying to say was that given the size of the body relative to all of the contact points, less-than-perfect conductivity in the body itself probably won't hold it back all that much. The current should have plenty of room to traverse through any reasonably conductive material of that mass. It's by far the biggest conductor in the circuit. The bigger the conductor, the more open the flow of current is, correct?
The contact surfaces are thus your bottlenecks. They are the narrowest pathways that the current has to travel through by a very wide margin. Even if they are all the same material as the body, the difference between the surface area of the contact points and the size of the body should be more significant than say, the difference in the conductivity of a copper body compared to stainless steel.
Because of this, I assume that a mod is essentially only as conductive as its contacts, which, given their exponentially smaller size relative to the body of the mod, will never be as conductive as the body - no matter what viable conductive material either part happens to be made of. The contact points will always allow for significantly less current flow than the body would easily accommodate on its own.
A mech mod is set up like a tiny pipe running into a much wider one. The amount of water flowing through the wider one is therefore limited by the maximum amount that can get through the smaller one. Say we have two systems with a narrow pipe feeding into a wide one. One's wide pipe (copper) is wider than that of the other (SS.) Which one is more water going to come out of?
If we take all of this as a given, then a stainless-steel-body mod with copper contacts should perform similarly to a copper-body mod with copper contacts. A copper-body mod with tiny, stainless steel contacts will hit weaker than the opposite. A copper-body mod with shitty contacts hits like shit... ...trust me, I have one.
I think it stands to reason that the connection points are far more likely to contribute to drop than the body. I'm talking about the number of interfaces, the quality/condition of the threading, the size and material of the contact points themselves, and hell, the size of the spring... ...this is why I stress the design of the mod over the materials. The body just needs to be durable and fairly conductive to do its job. Dirty, marred, oxidized threads will hurt you far more than using a less-conductive, more durable body material ever would. I prefer SS to copper for this very reason. The connection points between the threads hold up better, even if there is a very slight drop from it.
Again, this is just what my experiences, observations, and limited knowledge of how electricity works lead me to conclude. I can't pretend to know what I'm talking about. I'm just forming the connections that are there for me to grasp.
