Kirk, so you are saying to measure how much tension the string is at while at brace height? Not how much it takes to pull on the string .
Never thought of looking into that aspect!
This aspect is the single most important part about obtaining higher performance in a set of limbs, as well as shock and noise elimination. Believe it or not…. The highest performance bows are also going to be the quietest, and most dead in the hand.
It’s all about stopping the forward limb travel dead, and transferring the stored energy to your arrow shaft. The higher string tension at lower brace heights do this….. but of course your limb design decides how much energy is stored. The shape of the limb, taper rates used, and wedge configurations all play a part of it too…… there is no free lunch….. Kirk
