recently i was up at the far end of tremont fishing what i believe was lynn camp prong. fishing on a rock dangling a fly below me, a dozen fish must've nailed the fly as soon as it got any drag(not all at the same time, unfortunately). struck me as odd. I too, have believed that drag was a surefire turnoff for fish, but not always. i don't flyfish much outside of the park, mostly spinning for smallmouth or catfish. anyway, glad to hear opinions on the tippet theory.
