Hi Bullhound, I' ve owned both bows except the 2003 is the Mirage ZX with the twin ( now triple ) idlers on top. If it is a 2002 witht he CyberSX cam it is a great bow. I sold it to a buddy to buy the 2003 model. At 70 lbs. 29" with 29" Gold Tip XT Hunters it is shooting about 280-285 fps. I really liked that bow. The 2003 Mirage ZX was a nice bow as well but wasn' t very fast. It was changed to a triple idler system during the summer and is unchanged in 2004. Only Browning has now down graded the IBO rating to 285 fps which is more inline with what I found on the one I had. At 68 lbs. and 28" it was shooting my 27.5" Gold Tips at 250 fps, but the draw weight felt like 58 lbs. to pull, very smooth draw on that bow just wasn' t fast enough. Hope this helps. I also owned as Adrenaline SX and that bow was awesome. If you don' t mind a twin cam it' s a great bow. I was getting 270 fps at 62 lbs.at 28" with the above Gold Tip arrow.
