I don't think that heavy arrows with high FoC have better penetration capibilities may or may not be true, if I'm reading you correctly. I'm pretty sure it's a physical fact. Hopefully if enough people make some changes in the right direction we can influence the wounding stats. When I made the switch it was from info in here and not from a company that sells heavy stuff. But if the companies can market heavy and people buy in, well good for the companies pushing the change( chasing the dollar), and good for bow hunting. Trad archers have known about this new marketing trend for some time, it's about time us compound shooters got with the program.
