I haven't smoked cigars in a few years. But, when I did, it always seemed like the bigger cigars, Churchills etc., always packed a bigger hit, probably for no other reason than they are bigger cigars and you can get a 45+ minute smoke.I have been smoking cigars quite a bit this summer. Do you find the smaller ring grains stronger? The smaller maduras seem to whomp me harder than the churchills or robustos. At least in the ligeros, fire cures, and maduras.
I will will say that the biggest nicotine hit I ever got was smoking a Samuel Gawith cut black rope in a pipe. I think my Savinelli was even sweating.
