I apologize if some of this stuff is getting repetitive for you guys to respond to, I've been searching through the forum and trying to gather as much information as I can about this topic without having the opportunity to head back to Connecticut and take the Euro-nymphing class (now residing in Summit County, Colorado).

Anyways, I have found some promising water on the Blue River to test my luck at some Euro-nymphing here in Colorado. From what I gathered off the forums, the standard leader setup is a relatively strong butt section (approx. 5-6' ?), a sighter of about 4-6", and then the tippet section with the flies of choice. Correct me if I'm wrong please.

Still unsure of how far apart the flies should be spaced, and if using 3 flies, the anchor fly is between the others, correct? I also would like to know a little bit more about the tippet loop, I think I saw a diagram somewhere but I can't find it now. Something to do with a Surgeon's Loop if I'm not mistaken (and is it even relevant to Euro-nymphing?)

Any help would be appreciated, including links to where some of my questions can be answered.
