The variation is simply using CDL fibers for the tailing and wing / post instead of mallard flank feather.

The new s.e.d.g.e. is better called a Silly Little Thing consisting of one material - CDC. Tied in a single feather with the tip overhanging the bend for a shuck. Wrapped the thread forward binding down the feather to about the 2/3 point. Wound a couple layers of thread to bulk up the abdomen and then wrapped the thread forward ahead of the CDC to just behind the eye of the hook. Pulled the CDC feather forward to form a loop wing and secured it.

The variation is to get a little different look, and to experiment with the basic pattern in a different material.
The new fly was kind of a knee jerk response to a comment I heard on a fly tying video that was very negative about CDC - to the point that it is only good for one fish before it needs to be changed out. My experience is very different than that, so this morning I decided to do the simple, silly little thing using only CDC and then go see how many fishies it would stand up to.
Fished them both today. The hatch was a bit later, and by happenstance I ended up looking upstream …

… on some water that I’ve only fished once before, just about the time hatch got going.
The silly little thing got seven or eight …

… before it needed to be changed out. The second one got lost in some foliage after only a couple more takers. So much for good quality CDC being a “one fish” material.
The CDL variation also did quite nicely, taking the biggest dry fly fish of the day …

… at just under 17". I had one that was close to 18" before the hatch got started and a way downstream on that s.e.d.g.e. streamer, the PSC.
Along with a bunch more fish on the CDL variation, an original SLT got in on the action for its share of fun. Unfortunately, it didn’t occur to me to get out the one I fished the last two outings to complete the durability test. Oh well …
The catching was so good ( easy ) today, that I actually wrapped up before the hatch wound down. Not sure that says more about the fishies or the flies.
