i am just getting into the sport of bowhunting and was shooting some arrows into some hay bales with plywood behind it and *missed* the hay bales and the arrow went almost all the way through the ply wood. it got stuck in there and the wood chewwed up one of the fletchings pretty bad. i was wondering if it would be better to buy a new arrow ($2.50) or replace the fletching ($7.00 for whole kit) do you prefer putting on the fletchings on with a helical spiral? i will be getting more hay bales soon so wont be a problem for long just wondering what all of you do. remember this is just a practice arrow. thnx for reading.
