This was mentioned in another thread as being a good thing (I have no doubts that it is) when determining arrow weight and its effectiveness.
I mentioned KE...and another poster eluded to (

) momentum being the most important factor....and NOT KE.
I won't argue the point....because I have no idea. But I did ask this question.....and recieved no response.
How do you measure momentum.....to know if it's any good, or not.....and to determine when you are at a point of diminishing returns?
I suppose I could build a REALLY heavy arrow....and have a lot of "momentum" in my setup. But....at what point do you receive diminsihing returns?
This is of interest to me as I lower the poundage on my bow....and still try not to go with a light arrow setup.
Thanks.
