You may gather from my user name that I am partial to this vitola.
One of my go-to smokes is a lancero that shall not be named in this forum. The cigar I keep a few of on hand for outrageously special occasions is also a lancero that will not be named in this forum.
These are great right off the truck (except the Padron), and even better with a year or two on them:
Oliva V if you like a medium-bodied, creamy, baking-spicey, sometimes mildly cedary cigar.
Blanco 9 and 262 Paradigm if you want sweet, earthy, heavier-bodied smokes.
262 recently released an Allegiance lancero. I haven't tried it yet, but Clint has never rolled a blend I didn't like, even the ones that don't come in a lancero.
Padron makes a lancero in the X000 blend, although it doesn't carry a number designation. Has to be aged - kind of harsh ROTT.
If you can find them, PDR Capa Madura lanceros are smokeable fresh, and only get better all the way up to 3 years resting. Definitive Brazilian maduro flavor profile.
Others have mentioned the Illusione Holy Lance. Remarkable smoke in any wrapper. In fact, if you want to taste what different wrapper leaves do to a blend, try the claro, natural and maduros. The blend is so remarkably consistent that you'll easily detect the textbook flavors imparted and enhanced by the wrappers.
If you don't think you'll have time to smoke a whole lancero, cut it in half (not lengthwise
oke: ) and smoke the foot half first. You won't get exactly the same experience, as lanceros are blended to deliver a flavor profile through the entire stick. But if the cigar is any good to start with, you'll still enjoy both halves.
