Mike,
It's been the observation of others that once the branch is reverted then it is just that. If only a fruit or two between the striped fruit then I would buy too much into it.
Jon has a large Panache tree at his place.
One side is what a Panache is and on the other side it is completely reverted.
But the Panache is known to lose the stripes when ripe too. Was there ever any stripes? Even faded?
Are there any stripes on the fresh new branches?
Can you post close ups of your tree?
