I've used the spitfire 125'sand spirfire XP 125's for the past probably eight years and loved them. Had great success, lost two deer, one my my fault with a high hit and other to this day don't know what happend, I hit a doe perfect, had the best blood I'veever seenand tracked her for over half a mile until the blood trail vanished. I changed for this coming up season to monotechs, just because I want to start hunting turkeys with the bow and spitfires are expensiveif you miss. I like the idea of being able to sharpen them and reuse, but if I'm not happy I'll be back to the spitfires in a second.
