I've read in reviews how such and such cigar burned cool, even right behind the burn line.

Is this a desireable effect that one should aim for, or is it just some cigars that will burn cool?

Almost all of my cigars are quite warm in the half inch or so behind the burn line.

I have also noticed that I take fairly long puffs, but I do make sure to wait a minute between puffs at least. Maybe I should take shorter, less deep puffs more frequently to avoid those peak temperature spikes?
