So I have had a new Onza 3 for a few months now and **** it thru the chrono today. I'm at 29"dl, 360gr Gold Tips and 64lbs in draw weight. I shot 3 arrows and had 277 twice and a 278fps. Does this sound right or a little on the slow side to you guys. I have replaced the factory Hammerhead strings and put on a set of Korbins Custom strings. The ATA and brace height are exactly what the factory specs say it should be. I did not put the speed nocks on the string under the shrink tube like the Hammerheads had. Do you guys think I should do this? Just thinking this bow should be faster than this is all. Thanks for any help you can offer.
