I've been looking at Savs on sp.com abunch and I really like many of their styles (and prices!) However, I do not want a filter pipe. Smoked with a filter for a few puffs years ago, didn't like it, never again. So, who smokes 'em w/out the filter? Do you use the adapter/is it necessary? Does the adapter mess w/ cleaning? Any other Q's I should be asking?
