Quill Fletching

[GRUNDY]

Anyone know what brand/style fletching the quill arrows have? I refletched 2 of em with blazers and it changed poi from the others. About 1". The last deer I killed couldn't tell the difference...

I matched the offset with my bitz jig. If I get some time I might upload a pic of the adapter I made. It seemed to work real well. I'd like to see if I could purchase some of the same kind to refletch and see if the diff is the vanes, or maybe a subtle diff in fletch offset, etc...
Regards,
