At present I prefer my new Doc Grabow to my two estates pipes - a fairly new Stanwell and a 1960s Ben Wade. The Grabow smokes drier for me. I suspect that as my smoking technique improves, non-filtered pipes will appeal more to me. But I like the idea of being able to either use, or not use, a filter - and so I'm sticking with Savinelli right now for my new pipes. Two are on order and should arrive by week's end or so.
I'll now have five pipes when the two Savs arrive. Enough to keep me going for a while. I think my next purchase will be a Peterson, once my technique is better and I do not need the filter as much as I currently do.
