I had smoked nothing but ISOMs for the last 6 months and was not experiencing the pronounced difference from NonISOMs I recalled in day gone by. So I spent a week smoking nonISOMs, Fuente, LGC, and Punch. These had the same tastes I recalled and were quite good. This weekend I returned to my PUNCH PUNCH and MC4s and found that sharp contrast I loved that you cannot find in the smoke from a NonISOM. They seemed sweeter and more complex than a week ago. Anyone else have similar experiences????
