I just shot my 100 gr slick tricks standards and all I have to say is wow!!! They fly better than field points. I shot out to 30 yds and bulls eye every shot. Great heads and compact to my surprise, I was n't expecting them to be so small. I mean the 1" cut is there, but the furell is small. One question though....I shoot the Axis arrows and I do have the BH adapter rings for these arrows, but didn't see where it would help. Do I need the those rings for these heads on these arrows?? Anyone know??
