Frank,
The Lil' Goose will still put the position of the trigger too far back in relation to the jaw itself.........the " True" loop style releases you should be looking at are ones like the Scott " Rhino" , Carter " One Shot" , or Tru-Ball " Short-N-Sweet" .
These styles that put the trigger as close as possible to the point of contact with the loop is what negates the change in anchor usually associated with a transition from " Off the string" to a loop style.

Here' s a copy of a post from Eders I made to Vic (500fps) describing the style of loop I use..........This change in style vs what I normally use came from " JeffB" after he attended a seminar in NY with some top shelf archers with their careers riding on stuff like this. Thanks Jeff for taking me out of " Redneckville" .(see below)

First I will say that I have always shot a normal loop(what turns out the pros like Dave Cousins call a " Redneck Loop" )
Well if you just tie yourself a " Redneck Loop" and leave the normal bit of air between the 2 simple knots so that they aren' t putting any pressure on the nock sandwiched between....you think that you are OK. You ARE OK....but only OK. If you can do it, with a normal " Redneck Loop" draw your bow with a release and arrow and at full draw pull the string away from your face and look at the location of your release and the direction of pull.
You will see that the release is completely ABOVE the line of your arrow nock and that you are pulling on an " incline" .

What you want to do is this........
Locate your upper nock point that your arrow nock will rest against.......at this point tie in a nock set with serving about 1/8" in total length. Build it up enough and tight enough that it provides a good solid nock set.
Next fit an arrow nock you plan on shooting on the string. Make a mark about 1/16th of an inch BELOW the bottom edge of your arrow nock. This will provide a bit of " AIR" between the 2 nock sets.....this is important so that you have no pressure at all on the nock itself from below.

Now tie in another nock set starting at that lower mark and extend it TWICE as long as the first nock set....meaning build it up at a length of about 1/4" . That is the trick to this style........without the bottom set being DOUBLE the length of the top you will still be pulling above the line of the arrow.

Finally simply tie in a string loop AROUND these 2 nock sets(I like the knots to alternate or face opposite directions).....keep the loop very shallow to start because it will need to set. You want only about 1/8 -1/4" of gap between the finished loop and your arrow' s nock..........just enough to get your release in comfortably.

Now repeat that first excercise (again if you can) of drawing your bow with a release and arrow and look at the location of the release and the direction of pull...........you' ll see that BOTH are directly in line with the arrow.

Here' s a pic of my personal loop set-up on my 3D bow (Pro40 Dually)


(The 2 tied in sets are different colors just because I retied the bottom one a few days ago to give it a bit more length vs the original...same material different color that' s all)
You can actually see the ' Set" in the loop material made by the release position at full draw. You can also see the bit of " Air" between the nock and bottom nock set.

This style should help considerably to remove any " Release induced" nock travel problems.........it will promote much better nock travel in any bow, but especially Dual Cams where you don' t want to do anything to screw up what should be level nock travel in a properly timed set up.
