I know this ultimately comes down to persoal preference but I just wanted to get others opinion. How far down on the pipestem do most of you put in your mouth. I was looking at pipe pictures on Google similar to this dapper looking gent http://www.dsphotographic.com/g2/england/haworth/1940s-weekend/Howarth+1940s+Weekend+-+006.jpg.html and I was watching "Red Tails" and noticed Cuba Gooding puts a fair amount of the stem in his mouth and it got me thinking if there was any real advantage to placing the stem farther back in the mouth. Just wanted to get other's opinions.
