Cohiba Siglo, maybe
"Cohíba was originally a private brand supplied exclusively to Fidel Castro and high-level officials in the Communist Party of Cuba and Cuban government. Often given as diplomatic gifts, the Cohíba brand gradually developed a "cult" status. It was released commercially for sale to the public in 1982."
or a Montecristo as recommended above.
Try looking on the Hunter and Frankau website, they might have a list of who they supply in Manchester.
The only way I know of checking if a cigar is going to be a good smoke is to take it out of the tube and just squeeze it lightly along it's length, if there are any very hard spots, ask for another. Otherwise it might be like sucking a pingpong ball thru a straw. Some people say, if the cigar rattles in the tube when you shake it, it's dry. I'm not entirely convinced about that one tho, although it does kinda make sence.
Good Luck with the birth.
