I have successfully stalk-cured Corojo 99 as well as Piloto Cubano. My Corojo 99 grew so tall (9 to 10 ft.)—taller than the interior height of my curing shed—that I usually would take 3 or 4 primings (~3 leaves from each stalk per priming), and string those for curing. Then when the upper leaf matured, I would stalk-cut and stalk-cure the upper 6 feet or so of each stalk.
Leaf priming reduces the risk of in-field damage to individual leaves. Stalk-cutting and stalk-curing provides a decent cure, as well as minimizing the risk of flash-drying green, and is considerably less work than priming and stringing all the leaf. Traditions die slowly.
