I'm heere to tell you that Doc is right about the Slayer. Or might I say Slayr. 2004 was the first year I was with Martin and had a Slayr with Nitrous cams on it. Set up at 27.5" draw, 53# and 5gr/lb arrow it shot 308 fps.
Later in that year I shortened the draw to 27" and it still shot 299 fps. The only bow I ever had that came close to rated speeds.
I can't tell you how many Martin shooters wish they'd bring back the Nitrous cam.
