Leo, in my experience, they have a "window".
They suck, then settle down and smoke great for awhile, then they die.
It took almost a year for me to settle down the 1666's I have and they're smoking great right now. In a couple years, I expect they'll turn to air.
I try to burn the Double Espressos as fast as I can as soon as they're ready, cause when they go flat, they're flat.
It isn't gonna hurt to let them sit, so maybe revisit them in six months.
It could very well be that your tastes have changed, too?
