Just curious but why add all that weight to the arrow? What effect does it have on the balance?
To answer your question of "why?", I went back and pulled this explanation out of my original post...
I wanted something that gave me a sense of pride and craftsmanship, but more importantly allowed me to find my arrows easily once I got down from my stand and hit the forest floor
To explain further, it's amazing how different the woods that you've been studying, contemplating, and staring at for hours on end look once you climb down from your 20' perch. Before I started capping my arrows, I would sometimes walk over to where I knew my arrow was, and still spend a long time searching for it -- even though I had swore I had it marked with a landmark like an oddly shaped tree before I climbed down. Now, I never have that problem.
Now as far as the "all that weight" portion of your question... It's not that much weight. A couple coats of spray paint on the last eight inches and a few little stripings for decoration doesn't weigh much at all... I'm still easily able to obtain a FOC of at least 10% with 100-grain heads.
