Been using this knot steadily right along from my spinning tackle days to present when and where a tippet portion is required with very few....Notice I said very few quick attention is ALWAYS needed when tying ANY knot and I do get sloppy in the heat of the hatch, Sadly...

As well as the single AKA Duncan Loop for attachment to my fly,This is where I once in a great while will get the afore mentioned quick releases...Appears great care is needed when leaving the loop open a bit for added action to the fly.. also tends to allow slippage which can at times accelerate into complete knot failure.
It still remains the fastest knot I can tie!!!
