My ds3-r has some vdroop issues I'd like to fix. I'm not touching a soldering iron, and from what I've found there isn't a good working pencil mod for it. I did find this though, which the person says can be done w/ silver conductor. So my question is where can I get this, and how destructive is this if I mess up, and how reversible is it? Never heard anything about the silver fix. Thanks.
