DIY its a personal preference but I'm not a big fan of 4 blade broadheads. I like 3 blade and 2 blade designs. I had a coulple bad experiences with 4 blade ones. One of the best fixed blade broadhead designs I've ever used and resulted in the fastest kills (several dying within sight) was the Magnus Stinger. They flew extremely true when new. My only complaint with them is they were weak and would bend easily. You shoot one a few times into a "Block" type target the shoot again without realizing it was bent and completely miss the entire target. Not good for your arrows. Now if someone would make this design with a stronger material I'd be all over it.
