This is a good site to start looking.Look back in the archive(old posts).I just took a look back at some of the posts and this question has come up a few times to say the least.I know there was a really good post ahwile back from CJ maybe where he broke it down step by step with pics and everything.I could not find that exact post again but theres so much good info in the older posts,about ospreys and all sorts of good stuff.

Take a look i'm sure you'll find alot of helpful info...Trev
