"I've learned a lot of longevity/durability after having bows finally turn 5 plus years old and some having shots thousands upon thousands of arrows. There is so much more to the story than simply holding together for a picture and a few hundred shots."
I couldn't have said it better.
I still like to push limits on occasion, but find myself appreciating the best staves turned into bows 66" or so long.
My #1 osage selfbow is 66" long and 63# @ 28" and has been shot I don't know how many thousands of times since I made it in '04, and it's unbraced profile is almost exactly the same as the day I finished it.
