lasttango sent me a box of four primo tobaccos and I'm on my second one, my first bowl of Peretti's #52 burley blend. Most impressive. Like most blenders, Peretti is not itching to divulge all of the details of how they attain their individual blends, but it seems that this is an especially precise blend of various burleys done with a master's hand. It's nutty, sweet, subtle and evolving through the bowl. It's refined and sophisticated without being fussy. It has that warm friendly comfort-food aspect of burley but reaches beyond it for complexity and savor. lasttango especially recommended this one, and he was right.
