I get what Wayne mentioned about retrohaling, because you have to slide into it softly with little sips of smoke. A big haul off a nic puro can give you immediate irreversible brain damage.
My problem is that otherwise, I'd taste nothing. I also like to smell the smoke coming off each end of the cigar and sometimes inhale lightly to get even more flavors.
If I didn't retrohale, I'd get absolutely nothing from cc's.
Personally I think it's an indispensible part of cigar smoking, and think everyone should at least have the skill in their arsenal. If they choose not to use it, especially with very strong cigars, that option is always available.
