I hear what your saying Kirk. I like bows without a lot of preload cause I put a good bit of tension on the string long before I shoot but I've noticed those same bows tend to have a bit more play after the release...
Too much pre-load at brace can cause premature stacking, and put more stress on the working limb than it's designed for. Guys that twist that string up higher than the recommended brace height of the bowyer or manufacture, are shooting themselves in the foot. The archers that prefer an 8" plus brace height should purchase bows designed for that brace height rather than over stressing a bows limb designed to shoot at lower brace.
The reason you are seeing that string flopping around more on a bow with less preload is because the tension on the string at brace height is not adequate to stop the mass weight of the limbs forward motion.....
A good example would be a Straight D shaped Hill style D design that braces at 6" . If you have a 70# bow you'll find the hand shock and limb & string oscillations are much less than a 40 pound bow of the same exact design..... More tension on the string stops the limbs quicker.
The R/D long bows have much higher preloads for just that reason. They shoot much faster with a lot less hand shock and string slap issues because that energy is being transferred to the arrow and not wasted..... Ya don't have to pick your dentures out of the dirt either....
