It's weird for me. I've had 340 ICS Bowhunters, then went to 400 ICS Hunters because one I my friends said I should be shooting the 400's instead of the 340's. Then this year I got the 400 ICS Camo Hunters and it is the worst I've shot in years. I didn't shoot great groups with the 340's and I did awesome with the 400 ICS Hunters but this year I'm doing terrible with the 400 Camo Hunters. I'm looking to try another arrow and I was just wondering what size I should be practicing and hunting with with my setup. I'll do some research on the blue streaks. Thanks for the advise!
