I was skeptical for a long time. There were some reviews I read out there that always made me shy away from trying these. Said they were not durable and weren’t accurate with broad heads. Well that couldn’t be farther from the truth! Easy to fletch, super durable, perfect flight with broad heads, and waterproof. However, they did require tuning. Don’t think you can just slap these on and get after it. Your arrow needs tuning and the vanes need indexed proper for clearance. It takes some tinkering. I wished I would have tried these sooner. Saying goodbye to my feathers for the superior durability and weatherproofing! Accuracy is excellent.
