The only ones I've ever tried were Nockturnals but I've never hunted with them. Whenever I switch over from regular nocks I get a HORRIBLE tail whip! I have confirmed it by shooting through paper with both regular and Nockturnals. I don't mean to hijack the thread but if anyone has any ideas to help, please send them my way! I really wanna use lighted nocks but am not going to sacrifice arrow flight to do so. Sent from my iPhone using Bowhunting.com Forums
