One way to avoid that problem is to get arrows that allow you to add weight to the back, like Gold Tips. Adding weight to the back increases spine.
Another way to avoid the problem is to buy just one bare shaft of the type of arrow you want to try, and make sure that flies right with the setup you want to use before you invest in a dozen. It's not a bad investment. I have accumulated about 20 different bare shafts of various kinds of wood, aluminum, and graphite arrows over the years, so when I get a new bow, I can narrow it down pretty quickly with what I already have.
