There is a lot going on in that blend. It's one of my all time favorites. I bought so much of it I will probably never have to buy it again. I am working on tins from 2007/2008 timeframe. IMHO it just gets better and more complex with age.
I got in a new Pete Lestrade today in the PSB blast. Since it is my first Pete blast ( the others are all smooth)I have no way of knowing if it is any better than the regular blast. I like it. First pipe I have purchased since 2010.
