I believe the "Patriot" is un-filtered. Not a big bowl, but not a mini either. ALL of them are good. I don't have a freehand yet but I do have a Diplomat, Great Dane Spool, Patriot, Pony, General, 2 Legends,1 Washington, and 4 or 5 "Prides" The only oddball of the bunch is The Dane spool. Nothing really bad, just burns a little odd. Not quite as easy as the others to keep going, but I'd imagine it's something I've done rather then a pipe defect.
