I am having problems with blazers when I shoot my broadheads. I dial everything in with field tips, then when I switch to broadheads the arrows with blazers fly all over the place. My 4" vanes don't do this. I am not dogging blazer vanes. It's probably something I am doing. I wish I could get the blazers to work because I use a whisker biscuit and I hate having to replace my vanes as often as I do.
