Sorry to hear about that, Trucker. I know some have had success with the triples and some with the doubles. Totally a "different strokes for different folks" thing (as Mike's post just confirmed).
I personally have had success with the doubles (even the ones that came with the HeadBlade razor). I've since continued buying Atra generics (Walgreens, Longs, and SaveMart) with the same results. For that reason, I've chosen to not even try the triples.
