Perfect clarity goes a long way. My first, and only so far, experience with having someone else mod my saw turned out well, but communication sucked. Hardly any honest answers (at least it seemed that way). Every reply seemed carefully worded to imply the answer I wanted without actually saying it, so I couldn't trap him in his words, and it was impossible to pass an accurate judgement on the situation. All turned out well right at the moment I thought I got him, and the way it worked out made me wonder if vague answers is just his natural way of talking with no deceit intended.
