You will not see much difference with blazers because they stabilize the arrow by slowing them down, im not going to argue with you guys anymore because your already set in stone on your opinion. Sorry but simply testing your pattern isnt very accurate, feathers are 9 grains lighter than blazers 3fps, you need to shoot through a chrono and you will see the exact difference at 10ft then shoot at 60 yards then look at the difference in initial and downrange. Im strictly talking about speed and downrage speed. When your shooting 3d at unmarked you dont want to lose speed when want all the speed you can get.
