I haven't found them to be finicky at all. Easy to sharpen as well.
I used one to kill this big 2 inch shielded boar.....
Head buried in the off leg bone and had to pull it out with a pair of pliers....
Click Here That boar was killed with a 70# longbow....but the same head should blow through whitetails with your bow all day long.
Then I killed this hog also with the wide ACE and bow....but the wooden arrow stuck in a tree he was standing in front of and he broke it off as he left out for his 30 yard death run.
Also shot another nice gray boar and shot a 60 pound black boar the same weekend....at The Paradise but no camera that weekend so I didn't get any pics .... :(
But I like the head....I mostly shoot 3 and 4 blades....but if I do shoot a 2 blade, I shoot wide ones, and ACE's are dandy.
