reichenbach, that's good news. I have more Medico than Grabow filters, but I'll try them both. A Forums member also recommended trying
using half a filter, so I'll try that too. I have a new Grabow Royalton bulldog, and it seems to be a nice pipe, smooth smoker. Most of my
pipes are more mid-level and upper mid-, no filters, but I like some of the old U.S. machine mades and would like to learn to use them.
Thanks for all the good advice and info folks.
