Had a friend make a comment that a longer than necessary string loop will rob speed from the arrow. How can this be? Wouldn't it just make your anchor point further back? I mean the wall is the wall regardless, right? For the sake of argument, assume the draw length is the same and the only difference is a longer loop. For the record, I keep them as short as possible, just curious what you guys think.

I'm sure an overly long string loop will weigh a few grains more than a 'proper' length loop and extra weight on the string will rob some arrow speed. You'd need a really good chronograph to see the difference though.
I often use a very long string loop to compensate for my overly long draw length. For a bow with a 32" draw, I need an extra inch of loop length to get to my anchor. I've noticed no ill effects from doing this. So, I'd say that having the loop the correct length for you to anchor properly is far more important than worrying about an extra grain or two of weight.
The longer the string loop the shorter the effective draw will be on the bow. The shorter your draw the slower the speed of your arrow. As a rule of thumb you will lose approx 10 fps per 1 inch of draw.

Only if you reduce the draw length of the bow to keep your anchor points the same. Adding a loop does not change the physical draw length of the bow at all. It will effect the percieved draw length though and if you go too long it could mess up your form negating any actual benifits you would be getting from shooting a loop in the first place.
In some cases people don't shoot too long a draw length on the bow, they use too long of a release and it puts the hand too far back to get good form and shoot consistantly. Most releases people use are designed to be shot off from the string.

A persons draw length doesn't change regardless of how long the loop may be. Their arms don't magicly get shorter because you put on a long loop.
What does change is the fact that with an extra long loop one aspect of your bow goes from being set up properly to being set up incorrectly.
If a shooter needs more draw length because their bow will only go to 30 inches and their draw length is 31 inches then they shouldn't have purchased that bow in the first place. Imagine an extreme example of this. A person with a 30 inch draw length, such as myself, shooting a bow that is set to a draw length of 24 inches and me installing a 6" long loop to make up the differance. Yeah my hand may be anchored in the correct spot but you could hardly say that my bow is set up to fit me perfectly and my shooting will not be its best.

Absolutely correct. BUT... for those like myself who shot "off the string" for years before trying a loop may find the need to drop down a half-inch to accomodate the added length of the loop thrown into the mix. As I mention in my "how-to" thread on d-loops, today's "shorty" release heads help keep that draw-length loss to a minimum for sure though.
In other words, if I'm a 29" draw length when shooting off the string, and now add a d-loop that -- even as short as I tie them -- It will movemy anchor point BACK at least 3/8 of an inch ifI keep everything else the same.
Long string loop ????
