This feels like a trap... but I feel like I'm safe with my numbers, so I'll play.
I was gonna say probably somewhere between 1/3 and 1/2, but then I remembered the NC humidors sitting on my dresser, so now I'm like, maybe 1/4 to 1/3? But many of my CC's are smaller vitolas - in fact, that's one of the reasons I began gravitating toward CC last year - and I'm estimating by volume, so pretty sure I'm back up over 1/3 here since I can cram more minutos and marevas in a box than I can CG and robustos, maybe closer to 1/2 again now but still probably not quite at the 50% mark...
So I'm gonna guess, somewhere between 33% and 50%?
