I've been a Muzzy user for the past dozen years or so. I tried Montecs last year for the first ttime. I shot 4 (FOUR) deer with them and never had a blood trail - all were lethal shots. I saw one of them die and followed the path she took - there was absolutely not a drop of blood trail. They were dull out of the package so I did everything they recommended to make them razor sharp, but they were awful. I wasted over $80.00 for 2 packs of them.
