I shot tru flight feathers through an untrimmed biscuit all last year and could hardly tell a difference between them and new ones !

BUT......I switched to an offset fletch and I fletched my own arrows and made sure they were glued good & added a dab of glue to the front and back of each fletch ! It worked extremely well !

Currently I'm shooting Bohnings with a very mild helical and a new '04 biscuit and they are holding up great !!
