The Don Carlos Robustos are a nice smoke - your taste is impeccable. I had the opportunity to acquire some genuine Montecristo Cubans in Cozumel recently, but resisted the urge because the Opus Xs I brought with me were so good.
I've tried many Opus X's, but can't say I enjoy them as much as the Don Carlos. Juan Sosa has told me he thinks the Don Carlos is the best cigar made, period. But it' all a matter of taste, which is what makes it such an interesting pursuit.
BTW, I like Jim Suckling. I think he's a good writer. I was a charter subscriber to CA, but let my subscription lapse a couple of years ago when it became more of a "lifestyle" magazine than a magazine about cigars.
