Don't you like staining the arrow shafts with blood??
I trim the leading edge of the quill realy thin with a sharp knife and then glue the tips and sometimes wrap them down. Sometimes you need to turn the nock a bit so the fletching clears your hand better. I have less trouble with 4 fletch. Yesterday I stained a shaft pretty good though

looked close at it and the start of the feather had some fletching glue soaked and dried into it.......nicked me pretty good. I have been using cut feathers not burned, I wouldn't think there'd be much difference there.
