Just as an additional note to the main topic, I've gone through the "FGT = Letzt Stil" theory before, and never expanded on it because of other discussions i'd read up on concerning the notion. But as for this theory, which i'd finally felt comfortable posting because i felt i had some decent material with which to back it up, i have basically tackled two theories in one, here:

What the FGT exactly was for Ichigo, *and* how Isshin learned of FGT in the first place.

In the half involving Isshin, i've considered the notion stated a few comments above, that it was a technique Isshin learned from his own Zanpakuto Engetsu, and that it was a technique passed down only to inherited users of Getsuga Tenshou. While that suggestion is very possible, i consider it more unlikely, personally. Reason being, it just seems too coincidental: A secret technique, very similar to a Quincy technique in its purpose, execution, and aftereffect of losing powers... revealed only to the man who happened to have had a Quincy wife, and is also friends (for lack of a better word) with a Quincy man. It would indeed be a wild coincidence, but good theories rarely rely on coincidence; many of them are even concocted in order to explain coincidence. Not saying that i have a self-proclaimed "good theory", hahah, just saying that i am not personally relying on coincidence, as far as this theory goes.

Now, i'm going to give a different wording to my overview of the gist of this double theory, for the purpose of a better understanding of what i'm suggesting.

So, in the first half of the theory, Isshin tries applying the basic idea of a Letzt Stil to his Zanpakuto. Whether or not he learns it himself (i'm still bouncing around with this; doesn't matter too much currently, with the parameters of this theory), there's the notion of what Ichigo actually performed.

Let's say that Isshin was indeed successful in his attempt to create a new Shinigami move, revolving this Quincy inspiration around the Zanpakuto. You still must remember that Ichigo's Zanpakuto was not actually from his Zanpakuto spirit, but rather his Quincy spirit. So for Ichigo, he may have been aiming for what had been made into a true Zanpakuto technique (if Isshin was successful in its creation), but was in reality taught the Letzt Stil by his inner Quincy, who still maintained the masquerade that he was the Zanpakuto spirit.

What may really have been an actual Zanpakuto method, was overridden by the Quincy spirit, who still managed to make it appear to be a Zanpakuto-centered technique.
