Wish I knew how many animals I have shot through the mesh of my blinds with big two blade heads, centaurs, treesharks, bear razorheads and 200g Ace heads. Never had a problem with arrow flight, yes I've shot lots of 3 blade and 4 blade to and still great results.
It's easy to blame the broadheads for miss guided shots or no kills but IMHO with this many kills with the same broadheads sure proves a point for me. I have many videos to from in the blind and we went back frame or frame slow motion and saw no disturbances. Even with string trackers through the netting so take it for what it's worth, I know I will never worry about it.
Two blade!
3 blade!
Double with old 4 blade razorheads!
Just practice shooting through your netting with what ever you choose then you will be confident with your shooting. They all work just don't over think it and ignore the netting. Good luck!
