I started making some arrows for the Tennessee Classic--I hope everything is a little cooled off by then--The 6 short ones are 29" for my son and the new bow I just made him. They shoot like rockets out of his bow because they are so light. They are made from big-box bamboo.
The others are 32" long and made from cane I got from Mullet--I am not sure if it is hill or river cane, but I wouldn't mind getting more of it. It straightened out really nice, and the wooden pegs I put in the tips gave me a really good (for me) FOC, and I was shooting them really well from my bow.
