I shoot an 07 Tomkat.... I changed the sight and rest as soon I got it. I put them, on my now ex wife's bow. I was looking at an extreme and a Sword sight. I went with sword. The biggest reason 4 me was that the dealers in my area were out of both. I was told the same about both sights......... should be here in 3-4 weeks. I went back in 4 weeks and the sword was in stock and the extreme wasn't. Then I wanted to see the difference b/w the 2. I waited another 4 weeks and went back to look. No extreme..... sword was there when they said it would be. First 3 weeks. I went with sword. Great sight! Very durable, very bright. I had a problem with the light on my sword and I called them. I spoke with the sword guy for like an hr..... not argueing but just talking about hunting. I also got a new light in 5 days. No charge. And it was the updated model.
