-is the pencil mod too risky? Or is it safer than it looks?

-is the mod using resistors better?

-any other ways to accomplis it?

and did it really help a lot?

also, if you did the pencil mod, I'd like to know how you did it: I read through this article, and it seems a bit vague, it just says a few pencil strokes... more info on this?

Thanks!
