i dont know if i would be to worried bout wrinkled vanes, the vanes on the arrows my dad is shooting are wrinkled up from passin through our old imitation block target on occasion, but even still he can put two or three arrows side by side over and over, (he only takes 2 or 3 arrows out when practicing) so i come to say that it really dont make that much of a difference that i can tell, even when i shot vanes i noticed no difference in shooting straight vanes or if the was wrinkled. just my .10 good luck
