I clipped the end at an angle, I do this on all torpedos as the Colonel had showed me while he was in Yuma. I was told and find it true that it lets out more flavors. I am not sure why but it surely does.
It merely opens more area for the smoke to be drawn through. I use a punch on whatever cigar I can and found out on one cigar that clipping was the way to go. That particular cigar had a lot of tar and the small opening of the punch concentrated it and turned the taste bitter. When I clipped it the bitterness went away. I would think the angular cut on a torpedo would be somewhat similar, and actually make the flavors less concentrated. That cigar with the high tar was an Asylum 13 60 (60 ring).
Annalori, you should post an introduction of yourself, so that we know a little bit about you.
