Well that's your opinion. Yes those heavy BHs have more KE but a bad shot is a bad shot no matter what you're using. As I recall back before compound bows were invented we bow hunters were killing hundreds of deer a year with recurves and longbows that didn't come close to the KE of bows today. I know because I was one of those bow hunters. And since I've been using a compound I've killed dozens of deer with arrows whose total weight didn't exceed 425 gr. which included a BH of only 100 gr. And most of those bow shots were pass throughs. The design I was talking about making stronger was the Magnus Stinger 2 blade.
Now my opinion for what its worth is that there would be a lot less unrecovered game if the bow hunter would just sit and wait after his/her shot. I understand the emotion and sense of urgency to go after your animal but the animal isn't going to get any deader if you wait an hour or more depending on the location of the hit. I learned my lesson the hard way. Other reasons for a lot of wounded game is lack of practice and taking shots at bad angled shots.
Again, my opinion based on experience, I built a dislike for 4 blade designs. Twice I've had perfectly good shots turn out bad because of them. Both times my shot was perfect. 1/3 up the body behind the shoulder and the bh blade, I found later, hit a rib and diverted the arrow just inside the rib cage. The first one went out the gut in front of the opposite hind leg taking out one lung and the liver and the other turned 90* and stuck in the near side ham just barely slicing the lung.
Now your design does have a steeper profile which would possibly eliminate that but it is still a 4 blade design. While I admire your ingenuity your comment about "adult weight" seems to come off as being snobbish and really unnecessary.
