I have tried them and they are not for me. More drag than 2" Blazers so my long range groups taper off and have less range out of my sliders. Another reason is facial contact. I like to be as consistent as possible and it is harder to do when you have that type of contact.
Facial contact is the most common reason. Also need to use a drop away rest.
I hit maybe 3" lower at 80yds with fobs vs blazers. Haven't had nocks come loose either.
Tryem and see if ya like them. Like i said they have worked great for me.
