One day my grandpa took me to my house so I could get ready to go fox hunting with a guy from my church.He saw my Tonkin Cane arrows laying on my bed and he said I need to keep them out of the sun light and keep them flat but i have them flat.he said if I dont they will bend back(I got them pre straitend). Is he right do I need to keep them out of the sun light? If anyone knows please tell me. Thanks Kolton God Bless
