I say go with the Pro-Hunting topic too. I had to a paper on Wilderness Survival my senior year and I was able to stretch my paper out to about 20-22 pages. You should be able to hit 15 no problem. You could try doing a dispelling the myths kind of write. Have a paragraph dedicated to a myth about hunting/hunters then do another paragraph dedicated to ripping the myth to shreads. Good Luck on it! I bet there are plenty of people on here to help you out on it as well! (proofing, additional brainstorming)
