Has anyone used the Maniac broadheads and can give me some feedback either good or bad? I won four packs(an even dozen)from a hunt club raffle but I haven't been able to shoot them yet. I've only got a buck invested (raffle ticket) and I've seen the retail prices so these aren't cheap broadheads. I did put three together and it appears the bleeder blades feel just a little loose because of the way they fit inside the main blade. They don't use washers or rings to stay together but rather they just clip into place with a downward motion. I'm just wondering if I shoot them into a block target if the bleeder blades or even the main blade will come out when I pull the arrow back out (reversing the action needed to clip them into place)? I guess that action would be moot if they fly straight and go through the animal I'm using them on.
