I think you should pat yourself on the back, Bill. It took me a lot longer to get my first bends; months and months of frustration. And the #4 hole was my first bend also. Hole #6 is also easy to bend but people have trouble with it early on due to the tiny amount of tongue movement needed to produce the bend. It takes awhile to develope the control necessary to get the 6 hole bend.
