THEY WERE RUNNING AT 380+ FPSCLOSER TO 390 , AND MIDDLETON ONLY ADVERTISES 375 WITH A 350GR ARROW SO EXPLAIN TO ME WERE THE SPEED CAME FROM. CRONOS DONT USUALLY LIE. AND MY ARROWS RAN AN AVERAGE OF 396.6 THROUGH THE CRONY WITH A 350.GR ARROW. I THINK 375 FPS MUST BE THE MINIMUM SPEED FOR THIS MODEL OF BOW. ANYWAYS I DO THINK THIS 350GR ARROW IS TO LIGHT, I NOW SHOOT A 500GR ARROW AT ABOUT 348. FPS WITH THE LIMBS THAT ARE ON IT. THE BOW HAS LESS SNAP TO IT AND SEEMS TO WORK MUCH SMOOTHER WITH LESS STRESS FOR SHURE, I HAVE ATLEAST 1500 SHOTS THROUGH THESE CURRENT LIMBS WITH NO TROUBLE. I SHOOT THREE TO FOUR NIGHTS A WEEK AND GO THROUGH A COURSE AT OUR CLUB ONCE A WEEK AVERAGE. ACCURACY IS ABOUT THE SAME AS MY EXCAL 200, WHICH MY DAUGHTER IS KNOW THE PROUD OWNER OF.
