It would be a tough draw between the Opus PL and El Triunfador. I'd love to try an Oliva Serie V Lancero with a couple years on it, I have a feeling it would be outstanding.
If I were to put the lanceros I enjoy in order, it would probably go like this:
El Triunfador
Opus X Petit Lancero
LFD Double Ligero
Oliva Serie V
Don Pepin Garcia Blue Label (New addition, thank you Santa!)
Tatuaje Especiales
I'm sure I forgot a few, I'll have to go back through my reviews to check.
