Abdulaziz, you might already be aware of this, but Brigham only makes 100 of their "Pipe of the Year" pipes, so your 2011 POTY 86/100 is the 86th POTY for 2011 that was made. Currently, Brigham and the B&M stores which sell their pipes offer their POTY pipes to the buyers of the previous year's POTY first. We have a gent in our pipe club who just received his 2013 Brigham POTY, he has the same number POTY going back to 2010.
This all to say, that not only did you get a great looking pipe from a reputable factory/company, but you also bought a limited edition pipe.
Well done.
By the way, I typically break in my pipe using the "rule of thirds" but have heard SO many puffers speak to the "stuff and puff" method that I echo the thoughts above... go with what feels good.
Enjoy, and let us know how she smokes!
