BTW, did you agree regarding the % differences between ke and momentum when changing arrow weight or do you still maintain that...

Since momentum is increased at a greater rate, it has to have more importance than a factor that is increased by a lesser rate.
Sorry, I don't believe that just because both change, that they are equal in importance when determining which is the best measurement of penetration potential.
The context of my statement is that you are established with your draw weight. Like I said before, an archer should shoot as much weight as he/she is physically able to handle accurately. IMO it makes no sense to shoot less than that. Arbitrarilly lowering your draw weight simply gives away energy for no good reason. Thats what I meant when I said a given archer. So in this context, the only influence the archer has over KE and momentum is by changing arrow weight. When changing arrow weight, both KE and momentum move up and down together so it is therefore impossible to "equalize" KE and make momentum move simply by changing arrows. Of course it would be possible to put on a heavier arrow thereby increaseing both momentum and KE and then lower your draw weight which would lower both ke and momentum and because KE, unlike changes in arrow weight, changes at a faster rate than momentum with draw weight you could find the point where you have held KE equal and raised momentum relative to your prior conditions. This is what I would call a theorectical example. If you are comfortable shooting the weight you are at, it would make absolutely no sense to back it off and loose on energy and momentum too.
Once again, this is clearly not impossible. I gave you myself as an example. Arguing why or why someone should not shoot lower than their maximum is not relevant to this discussion. I do for a couple reasons. I want to be able to draw at odd angles, with no movement anywhere but my release arm. I want to be able to do this, no matter how cold or how stiff I may be that day. I gladly give up some penetration potential to get advantages in other areas. Hunting is not simply about pulling the most I can comfortably. It is about getting close and trying to gather advantages in many areas. Hunters do differ in what they consider important and that is why they put emphasis on other areas. Many hunters clearly choose to draw far closer to their maximum than they have to. I could choose the same, but I don't, and for reasons that I consider good ones. However, I'm absolutely positive that I could if I wanted to. It is not impossible and I could make the choice to key on increasing KE with speed or momentum with weight. It's all a matter of choices.
A better example would be my brother. He is a very strong person that can easily pull a 100 lb bow, and I mean easily. Does that mean that he should? Of course not. It's not necessary. He can choose to if he wants to. He chooses to shoot at 75 lbs with a very heavy arrow. If he wanted more speed and a higher KE and less momentum, it would be simple for him to accomplish this.
