Here's my take on aluminum arrows. Unless you're hunting really heavy boned game, you can find a heavy shaft that will work fine. As for penetration....experience has shown a straight-flying arrow will pass through most, if not all, North American big game. As for accuracy? Perfect field rounds have been shot with aluminum arrow with target points....low front of center.
I'm not sure what you are looking for in an arrow, but I would personally think a 2018 or 2020 would be plenty heavy enough as they are and will penetrate very well indeed.
Anytime the word "Extreme" is used it indicates there may be some problems in the final formula.
I guess I'm old fashioned but (to paraphrase) I think we are searching for and answer for a problem that doesn't exist.
