Just wondering if I really need to wrap my drop ins with foil or copper tape. I have several Malkoff's and a couple of Solarforce. Had a G3 with a M91 give me problems yesterday after a tailcap switch (Z59). it was flickering and doing all kinds of crazy stuff. I did all the normal tightening and cleaning with no luck. Removed the aluminum foil I had wrapped around it and it works fine now. Got me thiking if I even need to wrap any of them.
Opinions?
