All right Seacoast, I'll weigh in.
Most of the time I get 2 cigars on one lite. (I piggy back my smokes when I can).
There are sometimes that I have to relite to correct the burn. Maybe 5%.
About 5% of the time to keep a POS, too tight wrap, lit so I don't collapse a lung sucking some life into it.
5% of the time, if I have to go into a store, I cut just the lit part off and leave the blackened part.
I purge it also.
Truthfully I hate to re-lite.
More importantly, many don't "FIRST" lite properly.
That's for another posting.
