I WOULD LIKE TO SAY THAT I HAVE HEARD GREAT THINGS ABOUT THE MARTIN PANTERA. I ORDERED ONE W THE NITROUS CAMS LIKE THE SLAYER, I HAVE HAD ALOT OF TROUBLE WITH IT. IT HAS VERY LITTLE VALLEY AND HARDLEY ANY LET OFF IN MY DRAW LENGTH. HAS ANYONE ELSE HAD TROUBLE W THEIR PANTERA. HAS ANYONE ELSE SHOT ONE WITH THE NITROUS CAMS.
