Its always easy to tell Dan! I know one time I was doing lots of shooting with a six pack of arrows one summer with my Horton and even showed off with my one friends once that had the Titan Ten Point. I was shooting great with that group of arrows. Took all the field tips off to put on B-heads and noticed a difference in them. Weighed them at work and three where 85 grain and three where 100. I noticed no difference in them either on the target.
