through a bisquit id say they are a must. i hear they are the best fletching to shoot through a bisquit...tough and durable. wont wave and get all funky from the bisquit. i dont shoot a bisquit but my buddy does...his 5" vanes are as wavy as the Atlantic...

i shoot blazers. ive passed the same arrow through my bag target multiple times plus many others..passed many though a hard foam broadhead target. passed them through hay bales. out of all that i got ONE tinyyy rip. guess what? that arrow shoots as true as it always has...no waves, no wrinkles, no funkiness period...still straight and lookin good! oh...well minus 1. sliced 3/4 of it off with a broadhead...a good 2000+ shots with them or so...
