All of the cigars I had, occasionally, I have one, from uneven burn, tunneling, metallic flavor, exploding wrappers, to plugged.
In my experience, very very few issues with Fuentes and Padron.
Here are some, that tend to be problem child:
I had a few Ashton and LFD, that tend to burn un-evenly, but was resolved after a year or so of aging in my humidor.
Had a few of my recent box of My Father recently that tunneled. They are now being aged, will try it again in a few years.
Rocky Patel, metallic undertone.
Gurkha, famous for their exploding wrappers.
Finally, almost every brand and shape of Cuban, I have experience of them plugging,
, but those problem tend to go away when they are aged.
Hand made cigar tend to have problems once a while, I accept that as part of life.
