It may also be the cigars. Some cigars burn perfectly, while others don't. Try to smoke them at a slower pace, and make sure the light is well. Sometimes when it is windy I can't get a light like I want and I notice burn problems. Toast the end for about twenty seconds or so, then light the cigar by puffing it while holding the flame at the end. After you think it is lit, look at the end and the end should be completely lit. Then go ahead and take your real first glimpse into the taste of the cigar. Don't be shy when drawing the cigar as you smoke it, and give the cigar time as well. Don't rush it.
