Muzzy's are good only if your bow is perfectly tuned, and depending on the bow you still may need to sight in for them... I love the way they work though.

But Tight Point, and NAP Nitrons are extremely sharp and accurate, that is, unless your bow is way out of tune. To get your bow tuned bring it to a archery shop and also have them "mark the cams" so you can see if it's out of tune at home.
