I have an Elite Kure set at 65lbs and 26.5 inch draw. I’m looking at shooting a heavier arrow (550-600). Does anyone know the speeds of a Kure at this draw length with a 500+ grain arrow. I’ve tried using the IBO calculators but I’m not sure if I need to use the IBO set at full draw or at the 26.5 inch draw. The full draw is 335 and the 26.5 inch draw IBO is 300. Looking for some help. Thanks in advance.
