Thanks for the Theories. Now I have another excuse to play. I do have a greater helical on my feathers than Blazers, more I think due to the 2" vs 4" length of the feather. It was a thought I had when I was shooting the groups, but to be honest it just seemed too simple. I have not been shooting feathers on my compound for long. I usually only use them on my recurve, but decided to play some with it to see for myselfthe internet urban legend on dropping and weather was true.Just to clarify the poor rest contact issue though. I am shooting a Carbon whisker biscuit ( I suppose I should have mentioned that in the original post ) And I am getting great arrow flight and there is no way I could be getting cable contact on the Vectrix. They are just to far. I am going to play with refletching some feathers this weekend at different offsets and see what my results will be. This is one reason I love to practice out at40 - 80 yards. Little things show up a lot better the further you go away from the target and if I am shooting a nice group that far away, I feel much more confident at my 25 yard max hunting range.
