Can anyone explain why, what seems to be a perfectly fine cigar when you start to smoke it, turns into a soft sponge about 1/2 way through it? I had not one, but two of these last night. The first a "La Aroma De Cuba" and then a "Trinidad" both rubustos. They feel nice and firm before I light them, but then get real soft about 1/2 way through them, I dont know what causes this. Thank you. :?
