Looking at the authentic FBT Uptown

[Jspike21]

Hey guys. I've been eyeing up the authentic FBT Uptown mech at the vape shop I work at. It has a stainless steel tube, but copper contacts. I know how important copper is when it comes to conductivity, but I was wondering if the stainless steel tube will reduce conductivity even though it has copper pins. Any thoughts on this? Common sense tells me the tube should not effect the voltage drop, but I could be wrong.

It is quite the looker. The tube shouldn't affect the voltage, I prefer copper or brass tubes due to heat transfer, but stainless is fine. Then again, for any mech, I always want something with no top cap.
