Maybe I'm splitting hairs here, but it seems like longer working limbs are more forgiving; given equal OVERALL bow length.
Given "forgiving" limbs, the bows "forgiveness" can be increased with a longer riser, which really increases the overall length.
So in reality, a longer bow is probably a bigger factor in the forgiveness of a particular bow.
This could explain why a 62" bow seems to shoot better, smoother, more accurate in general for me than a 60, or 58 does.
I'm in the process of setting some further criteria for my next new/diff bow purchase.
Thanks for the responses! Maybe there's some more.
