Four bucks is for the gar, the roller, the transport, the tax, and the store.
Ten bucks to impress your friends how much money you have. Oh, and for the artful box, the embossed band(s), and the hype.
Think of K-cups. That's gotta be the least coffee for the most price in the history of brewing coffee, other than paying for coffee beans that a bat crapped.
Note how Bob said "similar proportions". He does not say "the same number of each type of leaf". One given habano viso leaf from the DR may be long, the next one short; one may be thick & the next thin; one may be crinkly & the next smooth. And, of course, a habano viso leaf from Nicaragua flat out is a totally different animal. In fact, you can taste the diff between Esteli and Condega.
We have the remarkable advantage that, once we settle on a blend that we want to stash, we don't have to roll our way through one bale of baccy after another, day after day. We're just running thru one pound bags. Hence, we can say that we like the hab viso from this bag with the piloto seco from that bag and demonstrate common sense enough to stop rolling that blend when either bag runs out. We get to control the process end to end. So we can decide to roll strictly thin viso with a light color from bag X, and go to town. With the store bought box, you are buying gars sorted for color by gals who are looking thru trays of gars wrapped by someone else who wrapped gars which were bunched by someone else, who got his filler leaves prepared by a team who may sort thru a dozen bales a day. We have a chance to be way better when it comes to consistency.
BUT: You also do have to be willing to chuck out stuff that doesn't fit the bill. You gotta treat your leaves the same way you treat your celery, where you whack off the white base and the green frilly head and stick only the nice middle stem into your peanut butter. You have to give up the notion that you are going to use every damn scrap of leaf that you paid for cause otherwise the old lady will give you grief. It's not like that. It's like picking out which taters to bake versus mash the rest of them. At the end of a rolling session, you ought to be able to look down with satisfaction at ample misfit sniggly ends and stemmy lil bits in your trash can. A willingness to chuck some leaf will also help your smooth draw as well. Look at some of Marc's pics, where he has his makin's all sorted out and prepped before he begins. I'm betting that's how he controls the flavor he likes. (Is Marc on this forum?)
Keep your filler dry as it can roll. Test your blend ROTT. Then, if you like that, roll a batch and leave it set for six months.
Here are two habano leaves, one from a bag of Vuelta Abajo and another from a bag of Esteli:
