I'm looking at getting a Parker Challenger or Mathews Ignition

Mathews says 278 fps 26DL @ #50

Can't find info on the Parker Challenger ? Also heard that model of Challenger is a knock off the Ignition or very similar...

It's a 2007 Challenger BEFORE they put the XP limbs on it....any clues or approx..?

It is a #50 DW also..
