i will only use fletch tape and have pretty much sworn off glue almost a decade or so ago.
the fletch area of the shafts needs to be properly prepped, cleaned. i use naphtha (lighter fluid). i've gone through more than 2 dozen rolls of bohning tape with nary a problem, but i guess a batch of bad tape could exist.
you need to also properly install the tape and the feather. if done right, and allowed to "cure" overnight, you will not be able to remove the feather's quill unless scraped off with a knife.
i also put a spot of fletch cement at either end of each fletching, for added insurance.
here's a hog killing arrow that laid in the south carolina woods for over a year - notice how the quills (rachis) are still *firmly* stuck to the shaft. the vanes got eaten by the elements and bugs. it took some serious knife scraping to get them off and ready for refletching.
