Default Re: duncan's loop-uni knot??

Correct Duncan Loop:
There are many web-sites that describe and illustrate a fishing knot that is variously known as a Duncan Loop, Uni-Knot or Grinner.
In Geoff Wilson's “Complete Book of Fishing Knots & Rigs” the illustration of the “Duncan Loop” is shown improperly since the initial loop is formed on the standing line side of the hook eye.
This improper illustration of the Duncan loop is a non-slip loop that does not have similar strength as the Duncan loop and to my knowledge has no name.
When the initial loop is formed in the tag end portion of the line after passing through the hook eye it can form a proper Duncan Loop.
The illustration immediately below labeled “Uni-Knot” is a proper illustration of the Duncan Loop although the snugging and final setting are not shown. The Uni-Knot is a later renamed copy of the original Duncan Loop.
If pulled down and set properly the final configuration of the Duncan Loop, Uni-Knot or Grinner are all the same.

I believe that some of the confusion lies in the manner of which these knots are pulled down after the last wrap with the tag end is passed through the initial loop. In my knot and the Uni the tag end is pulled in the same direction as the standing line with sufficient force to allow the wraps to wind back over themselves to form a neat spiral over the standing and tag lines like a nail knot tied back over on the line itself. If this is not done the knot will not fold over and therefore form knots that differ in their final configuration and strength.
