Oh come on Len, you know it's simple. I've watched you do it.[8D][8D][8D] I've also been there when things went wrong. A good proshop will find the things that go wrong, like manufacturing problems and shooter problems. I tell you, I used to take hours to get things right.(well I thought they were right) Now I've got the secret down, I take my bow to Len's place.PRESTO! It's so easy. But if you want to do it yourself, it can be done. And then take it to Len's place. Start with a good arrow/bow combo helps.
